First two sessions :)

I did two 40-45 minute sessions with friends via voice chat. I really enjoy this website, as I always struggled with poses, and am currently studying illustration.

I guess my struggle is with hands and feet. As you can see from pictures below, they are either webbed feet or grinch hands. I just want to know what everyone thinks of how my few sessions went, as I plan on using this site more often! Thanks! Also attached are some of my character concepts.

These are really good! You have some nice motion and a decent grasp of anatomy too! I think the only thing is line economy (which is something I struggle with). You've got a lot of little loose lines. Try using more swooping, single lines instead!
Keep up the good work!
