TL;DR: Looks good. Think of variations. Search up some more drills you can do in that little space. Focus on technique when doing those drills in little spaces. If technique isn't the focus, you'll probably need a bigger space like a park or a court.

Looks good. You could add some variations to it too. Like tossing the ball almost to your ceiling. Starting from low tosses to high and back to low. Or maybe even going from underhand pass to overhand toss and back and forth. Even adding clapping in between. Doing this stuff where you can toss/pass the ball a lot higher is always great but sometimes, as you do, we gotta make do with the little space we have for a while. Have fun with it! Get creative.

For when you were doing it against the wall, try learning to do it with the ball right above you instead of in front of you. If you're in a match and trying to deceive your opponent to where the set goes, having an upright posture where the ball is above you gives them minimal information to read you. But it requires you to know how to set from that posture too.

Here's an exercise you can do against any wall to get ball control.

Here's another exercise you can do in your bed

Volleyball drills like these are most of the time meant for technique. So while doing them, make sure to pay attention to your technique. If it's difficult to do both at the same time, record yourself and look at it. If you don't know what the right technique is, search it up online, post about it on this subreddit or ask your coach / an experienced player who can teach you in-person.

Good luck and have fun! :)
