I like it but...
1] Change the thumbnail that we see in the art portal. It looks a bit like something rated A.
2]The fingers appear to be a bit stubby. If I were to extend those fingers, the ratio of lenths between fingers would be off.
3] I understand that hands have wrinkles when they're in that postion. But unless your an 80 year old man, not that many wrinkles. Try to just make the smaller wrinkles less noticalbe and not so bold.
5] Everything else I didn't mention is completely fine
6] about 80% of the people reading this will not notice that I skipped the number four in the list.
3/5, 8/10, and I must say, you are pretty handy with your drawings.
Get it? Handy?
