First suit - critiques?

This is my first time posting here and my first suit. I started on this head a couple of days ago and just want a few more opinions on anything else I should or could do to make it better. I've never worked with anything in 3D before, so a second (and third, fourth, etc) opinion is critical, especially from others who have worked on suits and know what to add or subtract to make it look like a well-built head.








A few notes:
-I already started casting resin eyes. Where I've drawn the eyes in are where I will be inserting them and I have good vision from the 'tear ducts' save for my feet (damn cheeks).
-The black is just a foamie. I'm using these to try and achieve a smoother shape more easily.
-The jaw seems a little lopsided but I think that's because I haven't smoothed out anything in there, top or bottom.
-The character is supposed to have a long, streamlined look.



. For the sake of simplicity, I'm nixing the wings out of his design on the suit.

Also, where can I find decent wigs and does anyone know where I can perhaps find tutorials about incorporating wigs into fursuits?
