Anatomy Study - Hands

Hello. Here is a study of hand, numbers 1,2,3 were all copied from the first parts of the tutorial, then 4,5,6 are copied from my left hand :D Not entirely sure about my way of learning but I decided to copy things first based on references either from photo or real life. Then when I get used to it, will incorporate the things I learned to my future compositions, whether 2D concepts or 3D sculpts. 

PS: that disturbing stuff between my thumb and wrist are scars from trying to put a large slice of pork into a medium size oven... :D no I'm not suicidal... hahahahahha :D
