Handstand form check

I may be wrong but you need better shoulder flexibility to open up your shoulders more.

Try this: lay on your back on the ground with lower back(!), upper back, gluteus and entire legs flat on the ground. Round your chest inwards. Now in this position, raise your arms shoulder width apart(!) and bring them overhead. See if you can place your arms comfortably on the floor.

And you need to flex your thighs more and point your feet. Perhaps your feet are tight, for this I recommend rolling a tennis ball or lacrosse ball under your feet.

Also, you need more PPT and protraction.
