Hey Quake, this is a great improvement over previous works.
Some things:
more clarity. Less AA on the face, more flat clusters of color. At a small resolution like this the pixel clusters are very important and shouldn't be held back from their full potential.
The hood is probably the wost thing in this. That is, I think it's a hood and not hair? If it is a hood, it should not have a highlight. Cloth is not as reflective as hair.
The eyes are perfect.
