Huh, I like this a lot :3 It's a much better than what I can draw. I like the style you're doing here. I'd say keep it up; practice makes perfect. [Oh no! I said something so cliche! :P] My only minor nitpick is that you may want more detail in the eyes, but besides that I like it a lot ^^
I wouldn't worry about the eyes like what >>2 said, they are good as is, and look like a type of eyes I have seen in a good few anime, you could go into more detail but that is up to you.
