Not bad Chi ^^
However, near the top of her head your lines are pretty choppy but I like how they're nice, straight and smooth the more you get into her hair. So just try to keep the lines straight through all her hair and it'll look very nice :3
Also, I agree with Allstories. Even though you've never really tried realism, you should because it can give you better practice and you could develop your own unique look once you find your style ^^ Plus, it does help with your overall drawing ability in general!
Overall, nice job =D
