Comments on mask sculpture?

Hello all,

I'm in the early stages of making my first fursuit mask. I am aiming for a realistic wolf head, mechanically it will be built on a resin base which I will cast myself... If I ever get the courage to do it. At the moment I have a sculpture of sorts made, and I'd like some comments and advice from more experienced makers. I've never done something like this before.

Here's hoping I made the cut correctly... The images are kind of large.

Please comment on the proportions, would they be right for a wolf? Also, how far back should I extend the mask over my head for it to be stable? I wear glasses and I've tried to make room for them too, but I guess the masks eyes and stop could still be a little closer? Feel free to take the pictures and draw all over them. Any comments will be helpful.

First LJ post ever. Yay!
