Narrowed foam snout broken off at the sides

This more refined sketch model has introduced new problems for me to consider. The helmet has shown through the sides when I further cut the head back, in an attempt to make it narrower following the client's feedback. This model has helped me to understand the most resourceful, quickest way to fit the top jaw around the top curve of the bike helemt. By slicing through the eyeline, I was able to create two sections to the top jaw. I could then completely remove the centre shape of the helmet on the hot wire cutter by cutting through the back and around the bottom section of the top jaw. The hot wire sculpting tool has then been used to scoop into the top section of the jaw before both parts are glued back together. Any gaps can be filled and stapled for additional support.

From this model there are a few fundamental things I would like to change for my final outcome. I feel that the bottom jaw would look better if it fit all the way around the helmet, disguising the back half. I also believe I can get a better fit for the foam to sit on the helmet by filling areas with expanding foam.
