Is there anything else you would like the artist to know?
I haven't played Diablo III in ages, but I always loved the Act IV (Heaven) aesthetic, especially the early parts where you can actually see Heaven relatively untainted, all blue and gold and ivory. It's hard to find screenshots without much Hellish corruption, but here's a few images. (I picked the colors in the palette above by guesswork, so feel free to use the screenshots instead.)
