This looks pretty cool. I kind of wish you hadn't put what appear to be stars in the foreground that are completely dwarfed by the size of the planet. It gives the planet the appearance of ridiculously impossible size, since that would put its mass greater than some galaxies. Other than that, I really admire the imagery.
Awesome, I'm glad you got good use out of this planet I love seeing the different ways that people use my stock, so if you remember, next time, let me know when you use my stock so I can see the results!
I really like the depth in the piece, you created the strong impression that the dust is actually interacting with the planet.
No problem, it isn't a requirement, I just like to see the results. You actually did tell me that you were downloading it, I just never got a chance to see the finished product (though it's ok because I can see it now, obviously).
You can use it anywhere, and I don't require credit (though you're free to credit me if you want to).
