Patience is a virtue
Though apparently not something I posses :) After some great critique over on Blab, and everyone agreeing with my diagnosis, I have started playing with his head. I went back to my reference photos, and re measured, I thankfully found out that his head is actually the right length, but his eyes are too low down, which gives the impression of a shortened head. But before I made a cut or smooshed anything, I took a cast of his head using silicone putty (which I bought by mistake years ago) and Apoxie sculpt. I am now much happier with the idea of jumping in and messing around. More soon...
