I think this is a really good pic for a first one, Latios! :D It was a good idea to use the sprite as reference ^_^ That way you're sure to get the shading right! :D The only thing I would suggest is to make the lines a little smoother and rounder by using the Curve tool (it takes a little time to get used to, but is definitely worth it once you get the hang of it!) :D
Thanks so much for using my tutorial! ^_^ *hugs* Keep up the good work! :D
