This might not be the most realistic nebula, but I always like to think a bit outside the box when I create something space art related.
It's another collaboration of myself and *fmacmanus, who uploaded some of his watercolor images as stocks, which I used to shape the swan nebula. He then went ahead and added the 3D-elements in this picture (the ships, stations and the mechanical half of the planet).
I hope you like it and please don't forget to check Finn's gallery as well!
I love it!
You're welcome.
