Great work and great brushwork. I love the expression of the one in the middle.

There's a lot of great stuff in these. Is there something in particular you want critique on?

Very beautiful work...all three of them but if you put your self portrait beside these three it will look better, I think this is because of the choice of photograph from which you were drawing. The lighting was better over there and so was the background which made the colors pop up well.

Neat! I like the blue reflections on the second one, really shows the structure of a face.
