I wondered how you got that beautiful sky swirl. Thanks for this! 
I'm just techical nit-picking; it's still an amazing scene and a joy to look at.
TY for all the comments! You're right that I could probably get away with using less colors - I don't tend to keep a close eye on how many colors I use unless it's specifically a limited palette piece, though I'd like to start getting more meticulous about my color choices.
Amazing! This is a great scene and top notch work. but ... 192 colours! The image is excellent but it looks like you could have got away with 20 - 30 colours with the same effect and still had room for AA. Are you using brushes with translucency?
i'm in love with this already
