Unicorn WIP 2

I found this wonderful lineart from ReQuay of two Unicorns -[link]

I saw it and instantly thought Good Versus Evil, so I decided to work on the two unicorns.. maybe guardians of Good and Evil or something like that. I've got the evil Unicorn done..I think.. Lookin for suggestions. My thought was that since he's born of fire or whatever that his hooves are cracked and there's magma showing through the cracks. His horn was supposed to look cracked as well, but it didn't go the way I wanted it to. So he's got lightning...or something.

I'm not sure how well I like the Good one having the starburst..

Any suggestions, Comments?
