I was reading a Chinese novel that was translated into English called, Mystic Beast Adventures. One of the creatures that the main character comes across is a horse with elephant tusks called a....elephorse.
I couldn't help it, I thought about it so much I had to try drawing it! This one is the "king" of them, who was a scarlet color instead of just brown.
I wound up looking at warthog skulls to try to make it as realistic as possible. I imagine they wanted it to have tusks as long as an elephants, but then the poor thing wouldn't be able to graze and they were always grazing when they came across them.

If you're curious about Chinese novels translated into English, the site is novelfull.com. There are all kinds of genres and A LOT of stories. Just be warned most of them are very very long.
