I haven't been drawing for long time and I just thought I start again. I guess the best way to try to improve my self is keeping a sketchbook for crits.
Anyway this evening I drawed one study from reference (http://pixelles.deviantart.com/art/Erotica-3-71832803). Took me about2 hours ( think too long) to draw it. I think the line drawing was ok, but the shading sucks.
Second one is a self portrait from mirror. It took about 25 minutes or so. I'm pretty satisfied with that one. It's actually the first self portrait by me.
I also attached a step by step of the first one and also a Photoshop paint over to see the errors in proportions
(I edited post and moved the pictures, so I can change the thumbnail)
