Hey thanks for the wire. Overall its clean, which is aleays a good sign, but I think you could lose a few polys around the nose area at this stage and also the cheeks, especially if you are converting to SubD it doesn't need to be this dense just yet. You need to shape the polys around the mouth and eyes as if they were going around in a circle, basically get them to loop.
Keep going on the model dont uv it just yet though.
