Trying to study Tobe Sunaho.
(A) is mine. (B) is the original. Mistakes I noticed are proportional things, some color/value stuff is a little off, gesture is inferior (lost some of the subtly).
(C) Is a quick tachie-sort-of-thing I whipped up after, trying to apply aspects of the Sunaho approach. I'm not sure why I drew the face like that, usually, I do it a little differently, but I'm more concerned with the body. It looks like fucking shit. My end goal with bodies is to be able draw bodies in that real conventional galge kind of look. Pan is a good example:

I haven't been doing many studies of this kind of thing because I see how much subtlety they pack into the drawing and get discouraged as fuck. "Give it a year or two until you're more comfortable with anatomy" has been kind of my mentality. This is obviously wrong as OP points out. The artist Itiyann (いちやん) pointed out how he just did studies to get so good (and he's only 1 year older than me but he's been so good so long. Fuck everything). And if you look at the progression of his art, he made a complete style out of his anatomy even tho it was very lightweight in the beginning, and, with time, he packed on more subtly.
So, my question is, even when the amount of anatomical/stylistic subtly is blowing my mind, should I just stop being a puss and just dive in, or is there something that can help road map my way thru these amazing artists' paintings?
Academic-oriented anatomy resources (such as Proko and Hampton and Bridgman) I find to be only minimally helpful since they don't help with the most important part: actually getting the style to not be puke. plz help before I start breaking shit.
