A couple textures. These are fairly high resolution, made with a generator and edited in photoshop.
I have planet generator to do a few previews and then i turn up the settings to 3072 pixels by 1536 and 100 iterations, it runs for about 15 minutes; at which point i open photoshop, set the contrast to 100, click vibrance, set saturation to 100 and vibrance to 50. Resave as png.
currently have 20 textures
