This version is somewhat different to version 1 of the Kril'Dor skybox. Looking at version 1, while it was updated and different, I felt it seemed too much like a green version of Bespin and didn't really resemble a green, gas Planet, as such. So I had a re-think and thought about what this planet could actually be like in the STAR WARS universe. So overall, I thought this would be a more accurate representation of the planet, judging from the information featured in the Wookieepedia link, here;
The image quality of the Sky is nowhere near HD, but unfortunately there wasn't really any other way to improve it, without awful pixelation.
If you wish to modify and can find a way to increase the image quality, then by all means.. Have a go and I wish you the best of luck. Hopefully more than I've had.
