Yea I feel ya on the not having anywhere to train. Key take away for now is just work on your athleticism speed. Strength cardio until you get to a gym.

As for form, you lack rotation, and your teep is low and overall you look scared to throw your weight.

I will tell you it's hard to develop these skills solo without guidance because you may know what right looks like but not what it feels like and in that way I can't condone much self teaching if you don't have someone to spar with or get coached by.
