Piccolo from Dragonball Z

I was 16 when I drew this, it was one of my first REAL attempts at revealing my artistic side. Im still 16 but as far as I know im only good at drawing things that I myself find interesting. To me this is the best drawing I have made out of my other drawings I made on the same day that I drew this.(Goku, Krillin, Vegeta, Shenron, and Super Saiyan 4 Gogeta are the other characters i drew on the same day.) I would like a one to ten rating on my drawing and corrections that could have made it better so i can make an even better one next time. Excluding coloring it in. Thank you.
