May I make a small suggestion? His head size in relation to the rest of his body is a little...off. It's a bit on the small size. His neck is almost wider than his entire head. If there's a way to fix the size of his head, then you're gold.
Woah, my breathe is taken away I love it, I just love the way the eyes look and... I just love it all! This may be stupid to ask because I'm just clueless but what are these, light pictures of, like what they exactly mean? Sorry for the trouble '^^
