Good god...
Sorry mates, but this is hideous. Maybe if we got rid of that pixellated background and put the asphalt back it would work. All these forums with user info ABOVE the posts are starting to bug me. There is more LOOK AT ME than there is post beneath, and then there is a signature to boot. People with multiple badges also get a funny layout. The blue by the search bar is nice, but the lagoon and these aqua thingies and everything are an abomination. Maybe I'm just being over-critical because I'm PMSing today, but crap.

If you need some inspiration for something more balanced, refined, and self-complimentary have a look here. This is certainly better than that last one though.
Edit: Okay, I've cooled down. I like the layout. The shapes and whatnot are all quite nice. It's just those aqua-globes and this background. It's just... gaudy. We're TDU-C, not Marlin Travel. Can we have an option to go back to the good old asphalt?
