Love what you did with this author.. only a suggestion.. You should adjust the UNTOUCHED side of the image to the equal size of the finished side (just for clarity)...
...also, a little more attention to the neck collar is needed as it's all over the place. The angle to the neck is weird and the way it doesn't complete it's journey around the neck is glaring. It's a great idea, but if it looks wonky, that's all a viewers eyes can see and takes away from the terrific make up work you did on the rest of the piece. IMHO of course. GREAT JOB on the face
