I think you’re off to a really great start. Some of them are really good in my opinion, especially for quick 30sec.
I am noticing though that some of them have a proportion issue, and that is, the legs are too short. I’m not sure if the refference includes perspective and maybe there’s some foreshortening happening, but that’s something I would look into in order to make sure my proportions are correct.
