Incase your wondering, I intentionally made the arm on the right bigger because it's pointing towards the viewer. It's a very useful technique called "foreshortening" that helps to add depth to whatever it is you draw; I've done an excellent job of it here in my humble opinion.
It's not a self portrait, but it does eerily look like me... that's not good, maybe it is me? but I don't have a cat/dog!

I'll try to post something more serious soon.
