You're getting there! His legs still look a bit thick, though. Here is a reference. Make them a bit thinner around where they meet his body.

That is exactly what I was going to say. Also, in that reference picture look at Sonic's gloves and shoes. They have a white band above them. Also, if you can add it in there, Sonic has a small tail. I'm not sure if his arm is blocking it, but either way... Just pointing that out!
