1. Render is fine
2. Text is bad , barely visible
3. Background is bad , just C4D's won't do it good. "You have to smudge something first then put C4D" etc. Madara's eye in the background doesn't fit .
4. Don't get me wrong =] I just want to help ^__^
Check some sig tutorials in web, I'm sure Photoshop has lauds of them. Train background making first =] Good Luck
