Last night my friend ZiPo revisited my ponified avatar, which is more like an OC now, I think. Now it has more proper anatomy, more defined hooves, a bit smaller horn, more chest fluff and a spiked band, like the one on the neck, on a right foreleg. Unfortunately, ZiPo is very lazy, so I doubt he'll ever finish this sketch, nonetheless is looks damn good.
He also came up with a cutie mark, when I said the character was a blank flank. It's a black hole. Because I eat a lot and don't get fat.
I still can't come up with a proper name.
