Well the first thing I decided to play with was the neck, for both poseability and length. To me that was the number one problem with the figure.
I shaved off a lot inside the neck/shoulder area and it turns and lokks up/down perfectly now. And it fits inside the body better. The other thing I noticed was that the neck length is actually ok, it looks too long because the shoulders don't come up to meet it naturally. So I padded those up a bit, I will post a few test pics below. I shaved back the glasses quite a bit and the bridge as well. I noticed you left that Ray? It looks great if you take it back a bit as well. And then the hat, as Ray pointed out there are two hats here sewn/lined together, if you are careful you could get two hats out of it.
