Its quite monotone, which doesn't always equate to something horrible but coupled with the text which doesn't fit, style wise, and the messy c4d.. meh its just not for me I'm afraid. I'd go with a lot more colours and establish a more definite light source for some clean perspective.
i agree with everything said here. it all seems a bit thrown together, but it can be saved imo. my input: it feels VERY flat, it needs more contrast in color. lighten the lights, darken the darks and see what happens. There aren't any whites whatsoever and barely any blacks, add em. You could also try killing some(or all) of the opacity in the text to help create more depth.
