That's a bit depressing, as talk of death always is, but this is still a marvelous picture. I like the unicorn's build - he looks old, but not necisarily decrepit. And his expression looks just perfect - wise, accepting, and perhaps just the slightest bit afraid. Also, grat job on the littered skeletons. A horned mythic beast graveyard, eh? Interesting.
Keep drawing!
Eeenteresting concept. I like the uni!
