I am super psyched to be doing figure drawings. It's my first drawing class and I've always doodled and such, but I've never drawn as well as when I'm drawing from life. Most of those are 20-40 minute drawings? There are some five minute ones in there. I feel like I'm getting alright at the outline but I've never really practiced shading and that's probably my biggest problem. That and learning to deal with the fact that models do move.

Don't worry about the details at all actually, those aren't important right now. Details are only important when you want your shit to look expensive, but I'm guessing you're not looking to auction any of these off at the moment so don't bother with them.

This made me laugh. I kind of believe in that attitude I think since I like rougher/more simplistic artwork as it conveys emotions that can be more intense, but there's also a part of me who really likes the trickery that certain artists can do to make objects look tactile.
