Found this piece of concept art today:
"An early on concept for Kultiras when it was going to be a darker theme."
I'm hoping for a return to a vivid color palette (MoP-like) with Dragon Isles, as I wasn't a big fan of BFA's general muted color palette (though I can understand avoiding the color green after Legion).
Anyhow, I found this comment interesting and might explain some aspects of BFA's art direction, as a residual effect of the original theme. KT was originally going to be darker and gloomier (?) I guess, maybe tipping their hand earlier more about it being a sort of Old God expansion. Drustvar still retained some of that at least, but I'd imagine Stormsong Valley received the most changes in early planning.
How do you feel about the color schemes in BFA in regards to environment, transmog, etc?
