Moving to the beat

My oc Vaana who's pretty pregnant(yes he's a boy), he snuck off again to the schools stables and gored on some grain too so he's feeling quite full and happy. He's taken a liking of listening to some music his friend got for him. It helps his moodswings ^^; Pretty sketchy though I may go over it. I haven't ever done a pregnant centaur before.. and he's having twins! Well triplets, one dies though.. This is for an roleplay on http://www.acornrack.com/koigokoro/

I might color it... so keep your eyes open.
