This was originally just a doodle...and well, still kinda is. It's not refined in any way. But, I wanted to get this idea out before I lost interest. I might redo this later, might not. Not sure.
In any case, this is my MLP OC, Edgar, after he creeped into another pony's house, possibly looking for easy prey. Factoid about Edgar: He may be a homicidal, cannibalistic Poh, but he's also a coward. :) While he does possess magical abilities that could put some unicorns to shame, he still isn't invincible. He tends to prey on the weak, or to just catch ponies by surprise, with no one else around to help. He runs in fear if there is even a slight chance he might meet a foe up to par with him.
In this case, a particular unicorn...or pegacorn (this can be any pony you want, though I had imagined either Twilight Sparkle or the Princess)...finds him in some kind of a storage room. Aww, he's such a pussy. <3
