A dark, steampunky Brave-New-World/1984 -esqe Equestrian AU? Count me IN!
Really fabulous piece. The armor design is wonderful and the effect of mild confusion ('what has become of our princess' etc) + mostly awe and fear is really present here. A rather subtle but interesting collission of styles going on here which I think works out quite well, from the irl-horsey chest you rendered to the high-fantasy sortof armor to the grundgey expression and backdrop to the childrens'-book sortof mane. It's awesome that you got it all working together.
