I had a bit of a heart attack with your feet. Especially in exercises where things get more difficult you have to point your feet! If they are not tight I know for a fact that your legs are not tight either and everything wobbles. Handstands are hard. It is normal that at first you might be holding your breath pushing the water out of your legs! In general everything is looking much better. We just need more strength. You need to push a bit harder. More clean reps per set! More commitment. You got this!
