lol you should have posted in the sig thread and not hrere but oh well. Text is horrible, un original, plain, doesnt flow at all. Background looks terrrible, doesnt fit the render at all. Im pretty sure its just a filter. Render placement it bad, and render as a whole looks pretty terrible. All in all read some tuts.
Flat, overcontrasted, boring textures. Impact effect sucks, not realistic at all. Needs more color variation. The composition is non-existant.
