You're welcome. It's what caught my eye. As for the anatomy, trust me when I say that's the least of my concern looking at art. Unless an eyeball or nose doesn't end up where the fingers are on ACCIDENT then it's no biggy.
Read the previous comments about the bend being in the wrong place. The 4th bend does look a little like that but is far too far forward. Also the fingers are majorly too large. The tip of the thumb should reach the first bend in the finger.
It is a really nice piece but i have to agree that do to it being a quick sketch you did mess you the anatomy of the pointer finger. But overall you did a great job you have some real talent with this. Love the crosshatching for the shading effect and the bracelets are fa nominal as well. Two thumbs up ps: I know everyone is a critic but it helps just wanna see you be the best you can be
