I think it looks quite good. I don't like the text, and he looks a little oversharpened on the top of his head, but 8/10
Ew, link looks all weird, and too sharp. Don't distort the render's face. Really flat. I like the text. Okay effects. Good flow.
Its original, a bit bland though. The whole sig is completely the same.. effect, and the light behind link is supAr random. :mellow:
Yup, try to throw in some different effects than just a bunch of displacements or whatever. Not bad though, that's good practice for displaces. Keep it up.
