You are doing alot of practice! okay, i will try!
I think my text might be a bit unorganized since your video is pretty long and i find stuff worth mentioning in different times of the video. But i will do my best!
After watching the first balls i still asking myself how much you think when you are playing. I feel a bit rude that i ask this again, since i have mention it alot before so i would think you try to think when you play, but i do not really see it. Please correct me if im wrong. In example you are serving long two times in the beginning. First one, you miss the second block and the second one she gets the advantage. How is this possible? If you serve long you know a player at this level will loop the ball. Then you need to have the racket high and be ready to block well so you get the advantage. You can not be surprised that you get a loop against you. You also know that she will loop pretty hard since you seem to do a topspin serve, she will proably loop more slow topspin if you serve backspin or sidespinbackspin. You also flipped a ball in the begin. If you flip against an attacking player you need to be ready that they can loop back. I think i will see this more in the video but do not need to comment more about it since i believe, you are understanding my point. When you play you need to think where the next ball might come depending on what you do, especially in serve and return.
I also think that you seem to have alot of variation in serve and return which is good, but i think you really need to work on a playing style. Try to think what you are good at, practice that and try to use that in the match. Now it almost seems like you have no purpose with serve and return and hope for the best. In example, if you are better at attacking the ball yourself you should try to serve more short, push more short so you can open first and try to loop and get the advantage. I understand that i wise to serve long sometimes for variation but if you are better at attacking, your weakness is proably defence and blocking and when you serve long you will not loop first but you will block. If you instead, like my are very good at blocking it is smarter to serve long and push long since you can block well and get an advantage this way.
I think that you should always try to follow your playingstyle and use your strengths but we also need to try to change the tactics a litlle depending on who whe play against. It seems pretty obvious to me that she is good at attacking, then you need to try to serve short and push short and prevent here from attacking. In tactics it also is important to know that you need to change the gameplay sometimes. In example if you serve long and push long and she destroys you with her attacks then you need try to stop doing these things and try something else . Otherwise you will keep loosing points.
I have almost only watched five minutes now, so i might be wrong that this is the case for the rest of the game. she also seems better than you so it might be difficult. But it seems to me that in all the videos it is the above that is lacking. Not the technique or level of play, that is pretty high, but more of the above. Especially practicing on strengths and try to use them in a match so you do not play at random and hope for the best. If you just practice everything and not focus on your strenghts you will have to practice forever to become good at everything. It is almost a waste of time to practie things we do not use in a match.
I have a story about playing styles. In club that we share a hall with, there are some pretty good players. One play with long pimple and pushblock. He can barely do two things, pushblock and forehand loop. This is the only thing he practice and he becomes good at it, and he is able to get this play at a match so he win pretty much games at a pretty high level. It looks pretty ugly and he have no good technique. His teammates have much much much better technique and is overall better players but they practice a little of everything and do net get their game as much in matches so they can not use their strengths as much so they do not win as much matches as the pushblocking player despite having alot better technique.
I enjoy watching your videos and progress but i start to feel frustrated that you seem to have a problem listening to my advice about the things above. You would become a much better player if you did. Or maybe you do listen but have a hard time implementing it. I also find it extremely strange and it makes me confused that you seem to practice with very good coaches but yet they do not seem to talk about this. But maybe they do, but i feel that i do not looks like it. Please do not be angry if im wrong, i just say what i think. I think, next time you are working with a coach talk about the above mention things and try to focus less on the technique.
I do not know if i really need to watch the rest of the video and try to say what i think about your technique. i think you already have pretty good technique and should instead try to focus more on what i talked about above.
And maybe im wrong about what i said above since i have not watched the whole video yet, but it seems to be the pattern over several videos. And it is so importan that we can always talk more about it. But then again, i understand that it is difficult if you play against a somewhat better player.
I watched not the whole video, it was so looong! but parts of it and i still think that your technique looks pretty good and i think you play with so many coaches so they can help you with that. it is harder to explain technique online. I also noticed that it seemed like you played better and better and i think it would be smart to try to think what you did different when you played better, how was the tactics and what kind of shots did you play.
I think that if you just focus more on tactics, playing style and think more when you play you will become much better i no time and you have the possible to develop into a really really good player in the future.
Good luck! I hope i did not was to harsh, i did not mean it that way.
