Pippin Took - Sketch

Well, is a project I'm doing, and I want to know if you think it looks like Pippin... the reference is this image: [link]

be honest, where are the errors?

--------------

So, the sketch, is it better than the first one (down there, in the corner) or is it worst, or what?

_{The shadow are terrible because of the material, and cause it is not how it will look, is just the sketch, and I'll paint it, the paint will fix the shadows.}

What do you think? Please see the referense: [link]
