i disagree with above, i've seen too many tags with too many c4d's turn out great. It all depends on how you use them. You can use c4d's to create fx, placement can create flow and depth.. Here you used them towards your bg, which is okay, but you did not use them to your advantage. I recommend you look at some c4d tag tuts. You also need to work on lighting, blending, and creating depth. Also the tag is too monotone. Notice how the gears dude has the cyan light on his armor.. you can incorporate that cyan into your colors, and can really help out the color problem. dodge and burn some parts of your bg to help you with the depth problem. Place some fx in the fg, and add some lighting. also DROP THE TEXT, it's awful. keep at it, read some tuts.
