HARPG - Eos Ysabel X Unknown

Can't sleep, so I figured I'd might as well play a little HARPG.

Here's my mare Eos Ysabel and an unknown stallion. Nothing fancy, a couple of hours of work. Will scrap soon.
Since Bella's in foal with this stallion from the island (read her description if you don't know what I'm talking about), he's kind of a big mystery - hence the silouhette -, as is their foal. All I have in mind so far is a name and gender for the offspring, but I still haven't thought of a good design. A color suggestion (natural) for the foalie (*not* the stallion) anyone?

Gotta sleep now, it's 3 am. *slams forehead into keyboard*
