Now you're thinking with portals.

Yah it's a Portal sig. Yah it's a photomanipulation.

Please C&C.

I like how you made the portal in the floor and stuff, but the rest of the sig just doesn't come together well. You have a nice grunge background, but then you have the Companion Cube which looks like it was just cut out and pasted into the sig without editing. The problem with that is that the lighting on the cube is opposite to the lighting you have on your sig. The overall colours on here are very sporadic and don't really work well together (the pink, brown, beige, orange, etc). I think that if you stuck to 2-3 colours that were well-matched, it'd be very good. Other than that, the colours, textures, and lighting just doesn't match that well.

What's wrong with it?

I guesse its pretty good. You don't see me around these parts much, so i guesse theres nothing WRONG with it.
