This is my piece for the DWJ Art Challenge of the month! Sorry for the bad English, I'm from Germany XD
I used this image for the cobblestone ground: http://www.gerwing.de/cache/com_zoo/images/Slideshow-3_77f7ccf12c842a644e63e853f317c037.jpg

The Grimataur lives in human settled areas. He is a demon like creature and devours souls; once he got you, you can't hope to escape. Every time he devours a soul his horns glow and grow a little bit; in his thrill his eyes become deep holes glimming with Helheims fire itself. The Grimataur is the offspring of a Minotaur and a Firedemon form Hell. He is a very rare creature, but don't underestimate him for this will be the last mistake you made in your life. EVER. *Tatatataaaam*

I know, it's not that good (open for tips, still a noob ;)), but I know that I did my best for now and I'm kinda really happy with his horns and learned a lot.
By the way, our Grimataur friend here lifes in Central Park, New York. He's still a young one, no older than two to threehundred years and found a home in the famous fountain there and attacks unsuspecting bypassers by night. Like the unfortunate guy winding on the ground. Bad luck, mate, sorry. Don't take it personally.
