I really admire the style you use in your artwork. The way that you draw something cartoonish and then add realism to it is amazing!
What I mean by realism is that the girl has relatively right proportions (besides from the head, but it gives the right feeling. I like it very much) and perhaps the shading.
Every one of your artwork that I've seen (including the art for Pico Day 2012) are amazing. Keep on going like this.
