Hi, after seeing all the lovely artwork on conceptart and cgtalk, I've been inspired to start my own sketchbook thread. I'm not sure if i'm even artistically inclined but I quite like doing art at school, though we haven't done any figure drawing, so i thought i'd like to brush up my drawing skills and make digital painting later. I hope you'll help me on my journey by giving advice and critique. Um... after that long intro, I think I'll show you a few of the head drawings i did after looking at Rebecca Kimmel's drawing heads challenge on CG Talk.
So what do you think I need to improve one? I know i definitely need to improve on my shading, feauture placement and proportions (there's something wrong with the man's head shape). I'm not sure how to go about improving these though.
