I have an idea! 😜

.

A horse like This looking down onto a lake or something like This and looking at her angel reflection or a reflection of her as a foal?

Ideaaa #1! a horse in a jumping pose, or cantering with wings, this would be the background https://unsplash.com/photos/the-mountains-are-covered-in-clouds-and-trees-8DBFmGW-ejA

Also I think a bay or black would look best for the coat color, and maybe some sort of intresting face marking

Ideaaa #2! I love this guy for stock oh my gosh, here's the backround, It's more a spooky one, https://unsplash.com/photos/autumn-leaves-float-on-a-calm-lake-surface-M_8Hn8m3Pmc You could make it like kelpie-ish if that makes sense, probably a black, maybe green tinted horse, make the mane and tail long and kind of just flopped over, like It's a horse that just got out of bed ( I'm horrible at explaining stuff help- ) Maybe add red eyes too, or fangss

Ideaaa #3! Another halloween themed one, It's like trick or treat vibes <33 Here's the background, https://unsplash.com/photos/trash-bins-under-brown-leafed-tree-WUBX3nUoJAY maybe have a front view horse walking, I'm sure there is some witch hat stock and basket stock, that you could fill with candy!
