I fucked up. Felt like giving this pencil-ish brush a try. Although I kinda like the first poses the last one looks as bad as when I first started figure drawing. I'm not sure if it has to do with not committing to my lines nor caring too much about contour when using this brush or I just couldn't get it right. Tried to draw it again on the last minutes. I'll stick to the small simple brush for longer poses.

Would appreciate any advice.
