My style always gives the ponies awkwardly long legs - I just kinda like how it looks. Plus, I specifically gave R (one on the right) even longer legs - in the movie he's taller than the heroine by a good amount, so I just gave his pony design even longer legs.
He doesn't have a 'name' yet, since he's just a design I made up for a friend who hasn't named him yet. I don't think he'd get a name past my friend's screen name, which I won't share here, sorry! Thank you though!
