Baby drawing progress

I spent an additional 12+ hours today on the drawing bringing the total close to 27 hours. I'm almost done blocking in the tones. I started adding shadows and highlights to the left sleeve. About 45% of the way done now. Yay! I miss my art table but with our new office/craft room layout it won't fit in here! Instead, I'm drawing on an art board propped on my knees. It's very uncomfy and the angle is flatter than I'm used to drawing. I've been trying to think of a solution to this. The image below is slightly skewed as I have to stand on my tippy toes to try and take the picture. I'm short. :)
