Here's some drawings I've made in my figure drawing class.
As you can tell, I've made my teacher angry by forgetting to add backgrounds.
And by getting most of it wrong.
Usually, to get ourselves ready for the long drawings we do a couple short five minute charcoal ones.
To be completely honest, I actually tend to like those ones better.
They can be pretty abstract, but a lot more expressive.
These are actually supposed to be throwaways, done on newsprint paper.
I don't know what it is about them but I feel like they sometimes turn out better than the detailed ones.
This last one is my favorite.
