Background is very beautiful but I don't think it matches with the render nor is the Render blended in too good. It looks abit as if you just smashed him onto the background.
Fix list: blending, background, text The render is out of place, the text is to hiden, and the background is all over but with these fixs you'll be on the right path.
Agreed with Dark wood. There is no flow. The background is all over the place and the render looks like it was just smacked on top of the background Try moving things in one direction on tags like that and to blend in the render, I think having the colors match a bit helps. Also What I sometimes do is cover part of the render with whatever im using in my tag (Maybe some C4Ds in your case) So it looks like he is behind the C4D or whatever you use.. I think that helps the depth and blending a bit. There's also text... But I can't help with that haha, I suck at text myself D: Hope I helped a bit! Keep it up though! :]
