i agree with [TheCalmMindedTai] and [KitStarr], i actually started out drawing almost the same as you are now, and looking back through my old sketch book i've seen how far i've come. but if you want to get better at something practicepracticepractice. one of the best ways to do it [i didn't say easiest] is to start off with life drawing, look at people around you and draw them, but if you feel they move too much, there is always stock photos, and posemaniacs.com just look, and draw what you see. when you get basic anatomy down, you can start breaking or bending the rules, and make your own style. a couple words of direct advice, try making the hair look more fluid, and study clothing, how it sticks to or hangs off of people. kay, i may check in periodically. don't know about watching yet.
Salutations and proclamations, I see that you've watched me. Thank you quite kindly for the recognition, but I must know how you went about finding me here on the not-so-very-vast SA.
