'Be Creative': Sonic The Hedgehog

Original lineart: fav.me/db6ismc

I made the lineart during my English class. I was supposed to draw whatever I wanted and write five sentences about your drawing. Here's what I wrote, in case you don't understand it:

"This is a drawing of Sonic The Hedgehog. He is probably my favorite videogame character besides the half-genie Shantae. I've been drawing the 'fastest thing alive' since last year, and I think I've improved since then. I like how he has a simple design, though I find his top quill hard to draw at times. Other than that, I like him as a character, probably because his heroic nature is an inspiration to many."

EDIT: I shaded this thing, but that was the morning after I submitted this and I didn't have time to scan it because I had to turn it in for my teacher. The shading wasn't as good as usual, though I still think it was good.
