Please post below with some ideas!

I LOVE to do Dark themes and I have many stock photos ready to be used.

I also love dark horses like Black, Bay, Liver Chestnut, etc.

So Basically anything dark xD

It would be really fun to make though! :) Thank You!

A black horse standing atop a battlement or ruin. Perhaps with shredded cloth hanging off him? If you want a medieval look, maybe some arrows or wounds. A skeletal pattern might look cool, too.

#2

An evil Fae horse. Maybe it's wings could look bat-like instead of fly-like? Sharp, pointy little teeth and glowing eyes. Maybe a pendant around the neck.

#3

A horse that looks like a statue. You'll probably need to download some concrete textures for this. perhaps with cracks or cobwebs, as though he's been there a long time. maybe in an old vault or room.
