Light!
You got an impressive feeling of light through colored glass with those colored pencils; very well done on the colors and tones. The lines could use some work: the left eye is a bit off, and the hand as mentioned below; lines across the torso are also a little plain and don't really feel like they're representative of clothing over a chest. The general pose, however, really is reminiscent of a stained-glass window, good work there.
