Hey. I like the overall drawing. the shape it self. I like the colors. But I think you need to work on you Anti-Aliasing (AA) because rightnow, its blur. you see, AA is not just adding colors. its actually sometimes (a lot in fact) replacing existing pixels with a different color. so you cant really just go on and keep adding. try this for exercise. try to AA something while stying inside a 1 pixel outline. don't go out of that. well, you can even try it on the image you just made.
take care,
Kazuya Mochu
