I feel like the render is smudged too much; I think you could've blended the render with the wireframe. Also, I'm not sure about the white pixely effect. The lighting could be more on his face, too. I like the bg effects.
Ha ha for once i didnt use any BG effects or lighting effects its just the render duplicated ans smudged everywhere.
well mate.. blending isnt tht good.. the wireframe C4D u used.. not going guud with the render..and there is lots of empty space there..try to fill it out
Wireframes don't look good here. Try something that can either help you blend with the wire or get a new background.
