it is very badly rendered i would recomend planet renders and pick a good renders and also get some C4D's in it or some brushes and it will look so much better.
those renders are really low quality... im hoping these are your first or something... use more simple text and watch more tutorials... add boarder too
k, text is horrid, renders suck, bg sucks, and DONT ADD BORDER. i h8 them imo, they bring down sig quality alot. read some tut, goto planetrenders, register on the forums, they have a great set of resources, tuts, ect.
