Wow man, very good. Although the original doesn't have a beard.

Your use of textures on the hood (and maybe the book but it's so fluid it may very well be painted) give the piece a really realistic look while your work on his face and beard project a really cool grim fantasy type style. The contrast between the very bright tone and the shadows around his face and eyes adds a lot to the piece as well.

I'm a total amateur but I don't see anything I don't like, if people aren't paying you for this they should be.
