I want genuine critisism, not some guy with a superiority complex
If this was true, maybe you could try and actually recognize the criticism you've received rather than bouncing it back.
thank you, but what is wrong with my stroke? It looks... off.. :|
There's no posture, no focus, you're not doing anything structural that will allow you to repeatedly train a good stroke.

In the video I am using a Yinhe T8s, Joola Rhyzen ZGR (Black, forehand) and Loki T3 (Red, backhand)
You could be playing with a Golden Viscaria but that doesn't fix the basics.
My advice, if you actually want to take it:
You look like you're goofing off. If you usually do better than that, record that instead.
You're more focused on the camera than the play.
Make sure you and your friend can play FH to FH at least 50x. No high balls, nothing fast or fancy, just make it a little game. 50x is a very low bar here, if you make it go to 100x, 200x and then as far as you want.
White ball vs light wall and light shirt is horrible. Because everything else is light I'd say get a couple of orange balls.
Stop wasting precious money on gear. At this stage you'd be just as well off with an old premade as you'd fare with your current setup.
Keep your current bat and use it for at least another year. Don't change the blade for another 5 years, don't change rubbers unless they're broken and replace it with something as close as possible.
Also, without the context of seeing what the other player does, it's even harder to judge what you do.
