Not bad...but I also think it needs a lot of working on. I would recommend pulling a lot of those vertices and points to start tweaking up the model some more, particularly the eyes, nose, mouth, and chin. Also, try to eliminate that "ridge" on the forehead. I had that same problem too once on my head model...try pulling the points in that area back some more closer to the forehead, and then of course smooth the area....maybe that can eliminate it. It is just a suggestion, it worked for me. Good luck on that model!
