Your head looks just fine to me. I've always been a little paranoid about how my head looks in the back. It's not round and smooth. I have some assymetry going on. But I would still rather be sly. I figure my head is fine because it's mine. I haven't seen too many "perfect" heads. We're all different. I'm becoming more comfortable with the way I am. Who cares what others think? Sly is the greatest! I look in the mirror and am comfortable with what I see, so why should anyone else's opinion matter? Be sly and proud, bro.
