Wow I love the red, and the different shades you used as the left side went into a shadow blends really well. The skin-color is great, and I really like the color blue you used for the letters. I don't really have any complaints. Great job. :3
I love the hair, and the eyes. But it seems like you just like using one color for everything. :/ Maybe try something with more background to it? Test out your skills. :B
