I feel like this drawing is very unique and you used the colors very well. It is a very nice balance. I also feel as if the left eye is slightly larger than the right eye but I can't be sure. And may I asked if you used stippling techniques? I love the intensity of the eyes; it really strikes you with a piercing look. I feel like just maybe you could have done a little more with this piece but that's open for debate. And the gradation of each color is very clean and simple. Overall it is a very nice composition. Good job!
