The one on the right I drew in 2007 I think, and the one on the left I drew today. I think I've improved over the years. (Okay, I know I've improved over the years.) So yeah, that's some random pichu costume I drew when I was once bored. :) happy face.

[EDIT] I didn't expect this to be so popular (by my standards)! Alot of you have commented saying that I've improved heaps (which I have) but just so you know, the one on the left is not one of my best drawings. It was a style of "chibi" that I drew for I while. I could draw way (well not way) better back then, it just happend the picture I chose wasn't a good one. But I still apreciate all the positive feedback!
