... and I am not sure I am getting better at them. 

Here are today's bricks:

I feel like it's all about shading and value, but also probably about being more precise with my pencil strokes. I could clean up the outside some with an eraser, and maybe use a white colored pencil to clean up inside, between the bricks. Let me try that.

I think cleaning them up helped a little, but I clearly need to continue practicing. 

Stoopid bricks. More figure drawing soon, I think. I promise no more bricks until there's real progress.
