Very nice hitting overall!
I'll let more knowledgeable people give you more detail advice but here are a couple of minor observations from me:
- You could do more weight transfer on some of the FHs- I never once saw you step into the ball, although you seem to push on the back foot.
- More adjustment steps before some shots
- Keeping head still/eyes at contact point through the contact.
Overall it looks great man, imho, for amount of tennis you've been playing! Keep up the good work!
