I think you guys are putting way too much emphasis on physical attributes. Hair and eye color can be changed, as can physique by working out. Height doesn't really matter that much in my opinion unless you are going to have him stand next to a ruler. Hugh Jackman is 6'2" in real life and the comic character of Wolverine is only about 5'4" and that didn't ruin the movie.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. ... The piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
~ Howard Phillips Lovecraft
