Very nice background. Simple, yet it's full of subtle hints of there's out there. I like the soft white from the clouds and how they are nicely balanced with that soft gradient to black at the top. It's very pleasing to the eye, and it makes my desktop look all floaty and stuff..
Great image pack as well, I totally dig the various res options. Too bad a lot of people (myself included.. ) don't package their wallpapers in nifty res packs..
I don't know if i will have time yet, but would you like to make a colab using this wall? I've been meaning to model something sky related, like a cool blimp, or some airplanes, and your photoshop skills could really make it all very cool
