Excellent job Marshall, there is nothing better than Photoshop for this kind of thing as showcased by this image!! Agree with Randy re the little gaussian blur on the collar, and the layering technique suggested, maybe a less advanced way is to try the blur tool which can also do a good job. I have some great books to recommend if you need to learn some other ways.
