I like it, but those little tufts of . . . hair(?) . . . on their hooves are just, eh. I'm not a fan of that particular stylistic quirk.
Which is a really negative thing to say, but it's honestly the only thing I have trouble with. I get what it was going for, and it's actually a really good way of putting the detail of a hairy (furry?) fetlock, but there's something about it that I just can't grok.
Great picture otherwise, though. Severely huggable pones ya got there.
