Backgrounds: Galaxy attempts

I made these using Autodesk Sketchbook, they are free to use as long as you credit me for making them.

I never see green galaxy patterns, so I thought it might be fun to try to make some using green, and I really wanted to use a light green galaxy pattern for a future artwork, needless to say though the light green one turned out awful, and will probably murder your eyes if you look at it with your screen brightness all the way up <~>
