Have all the puns been used up - nah, not quite...
What a nebulus effect you've created there (had to work for that one), the grain shining through the stains bring this to life.
I can see you've created a star in the centre, if I may, a nebula is the birthplace of stars, it might be able to take a few small shinies as birthing stars scattered around it.
As ever, something completely different and amazing to look at, you never fail to amaze. Thanks for posting.
