Well 1600x900 is the best I have for this version. Originally this started off as 1920x1200, but I ended up cutting down for my laptop resolution - 1600x900. I do have a PSD that's about half way done and I could complete it, but it just wouldn't be the same.
pretty cool, colors are awsome. i think you should've painted over some parts of the nebula though, like the right middle part. i like the flares of the stars aswell, although the smallest stars are a little distractring to me. overall a great piece!
