well you should have changed the colors of the C4D's to match the scene because the colors are very random and don't match.Thats the only thing i can see
1. Don't like the colors of the C4D's on the right.
2. I think you erase some of the C4D on the right side. (IMO)
3. Yeah, the text isn't good, I suggest going with a light color.
4. Background could be darker.
