Your speed painting skills impress me! She has such a sweet face, and everything seems to be sparkling and jovial. I think my favorite part of this piece are the little white dots everywhere, they give it a unique sort of galaxy/nebula feel, along with the intelligent placement of color in her shirt. I love the transparency in the shirt by the way, you pulled that off very well. I also love the headpiece, with the cute little rainbow pathway on it. <3
Now I realize this is a speed painting, but one eyebrow is quite a bit higher than the other. I think both would fit the face quite well (as in, low eyebrows or high eyebrows would complement her face well), if not for how uneven they look now.
