What should I change/add to this one?

nice start
remove the ripple effect from him and add some textures on the player and lighten him up so that he doesn't look like a part
also lower the opacity of the texture withe the lines left of him
of the bg add some text and a border

The BG looks very good. You need to get rid of the ripple on the render. Lighting up the render with some good textures. I would use a modernish font for the text. It looks nice mate. Kiu.

looks alryt get rid of the greyscale on the render add some light textures hava look at some render tuts and u will b fine oh and add some text
