Well I tried making him just as dapper and handsome as he was as a human but I'm not sure if it really worked...
Of course our demi-god would be a alicorn, his brother's going to be one too. I was going to dress him all up fabulous, but his helmet has been condensed into his horn and his cape his are now his wings. I hope the amulet and leg-braces are enough to satisfy you guys. Of course he still has his amazing cheekbones, even as a pony he'd have them and asdasdasd....
Just. Yes.
You can't see his cutie mark form this angle but it's supposed to be the classic roman happy/sad masks. I forgot what they were called, sorry.
