I like the picture, although he seems to be slightly wall-eyed? And I think his chin is larger than that... there's something odd about the shape of the face. Nice use of color, though, especially with the curly glowy white stuff (regeneration effect?)--it's a nice, unobtrusive accent.
Also my inner nerd is going he's not Doctor Who he's the Doctor asdfja;oe /accuracy nazi /obsessive-compulsive ...sorry.
