Making Hot Cocoa

This is something I drew, which was homework for my drawing class, and I had to draw a mug this week. I could only use shading pencils, and shaded in black, making it a black and white drawing...no colors ;3; but I like how it turned out, especially Tamama X3 I made his face all chubby because his head is resting on a table while hes making a cup of cocoa!
