Character Bust Silhouettes Evolved

I took one of the busts from my previous post and developed it a little more.  I didn't like the shape initially but after this set of bust sheets I'm liking him a lot better.  My character busts give off an elephant/ rhino sort of feel.  I imagine him being very brutish and strong, but passive if left alone.  I created a few with shaved off horns and I started drifting off into space wondering why he might have had them removed.  I can see a story might be in development with this creature.
