Holy cow, I drew something!

This is the first thing I've drawn in a long time; I figured I'd start with something simple, and Sonic characters seemed relatively easy to do.

I started with Wave, who I was rather pleased with, though I can see some errors, such as her pants are way too big; she wears bell-bottoms, but this makes her look like she has tree trunks for legs. I followed it up with Cream, and added Cheese and Vanilla to fill out the page, and had them reacting to Wave in some way. I thought Cream came out good, but I'm disappointed with Vanilla; she looks about one step better than what you'd find at Badly Drawn Kitties. I'm definitely going to try and redraw her.

If anyone has some constructive advice, I'm all ears; I'm going to try and redraw all of them for practice, and any help will be appreciated.
