Please don't keep flooding us with that much average wallpapers. Just make one really good wallpaper instead of making 10 that noone will use... Just an advice
Cut down on the contrast, it's very sharp in the eye..and cut doen on the level usage.
The other one:
the black edges are very choppy: solve this with the smoth thingie(cant rember name )
i like the logo besides "half life 2", but it is also a bit choppy .... no idea why.
