This is really good. The anatomy is pefect. The shading is wonderful, you seem to have a way with the fabrics. The composition really works well. The pillows and thin shelf bed are good in carrying the theme of insomnia. Overall, there is a deffinate feeling to this piece and it reflects it's title perfectly. I'm impressed you've done so much with such a common medium. Well done. That's enough gushing, I'm going to try to sleep now. Wish me luck.
