EDIT 2: Did a new shape fix with less shape deformers than before, with a rectangular bounding box, using only 4 corners at a time to deform it either horizontally or vertically. Only increased the amount of deformer points on the box in order to fix a rotation issue at the tip of the snout. It turned out looking slimmer than the previous model and a whole lot less stretched out of shape and I think it looks much better now.
EDIT: With the permission of the original uploader I have made the model free and available for download.
The 3D model was originally uploaded in the link below, but I just wanted to see if basically just removing some of the vertical skewing of the piece would make it look better and I think it did:

Besides the shape fix I also scaled it up to about full size, with the limited information I could find on the real skull's size.
