Coincidence?
I drew similar sketch days ago for Jagon from [Urban]. You practicing anatomy? Don't use my sketches for that (if u are), they are not 100% correct. :P
Okaaay, maybe I'm paranoid with old age. :P
Damn, I need one of those, training dolls. Right now I have a wooden dummy that is used for poses but its just basic stuff. You have to ''imagine'' a lot...
Anyway, great work. Some mistakes but its understandable since you are practicing/starting. Will u try face also or is this only body/anatomy tryouts?
Advice: use lots of helping lines, u can always dispose of them later. They do what they do: help.
