Wow! I love your style! I love the colorfulness, and the kind of very stylised face you do with the big wide eyes. I love your hair too. To be constructive, I think the main flaw in your pic is the hands. It's not that you draw them as circle -I often do that too, I like how it comes- but they are very tiny compared to the rest of the body. Maybe you should try to make them bigger. Also, the sleeve of the arm you're lifting would probably not stay stiff as it is, but fall a little and have more folds. Aside from that, I love the pic. Hope that help, and keep up the good work! :D
