Let me just say first that this is an amazing first model. I still have trouble with the human form.
Now on to the crit. The ears don't seem to be sticking off the head at all. All ear, even ears that lie against the head, still seem to stick out a little. These seem molded right out of the "clay" of the head. It makes it look sculpted rather than a 3D model.
That is the only crit I can come with right now. Great work.
