Wow, really awesome. I love the colours and how you did the nebula Only one little thing: maybe you should try to use some more and different star brushes. Unfortunately they look the same here in this pic.
Really cool piece, love the nebula and the colour scheme is awesome. I think perhaps it's cropped a little too tightly, the elements in the composition do with just a little more breathing room. Also I would move the smaller planet downwards a little just so it's more visible contrasted against the bright nebula background. Overall though a great piece, keep it up
This was almost going to be the colour scheme for my last piece, before changing my mine and realizing I might save purple for something better fitting
I do spy a clone of the gas giant planet (texture-wise at least) I normally jump to see stuff like that right away But the nebula is fantastic, and it's so rare to see a purple space scene still look and feel so natural
