I put up a bunch of space wallpaper done by Greg Martin. All these images were publicly displayed on his website, so I assume it is alright for me to publish them.
I always like having space artwork as my wallpaper background, but I haven’t found an artist that is in the same league as Greg Martin. If anyone knows any good space artists please leave a link as a comment. Greg Martin also has a few tutorials on how he draws space scenery. The planet and stars you see in the background are all based off his tutorials. I think they turned out pretty well, especially when I have never drawn a planet or a star field before.
