Sleipnir Sketch

Trying to find my way of designing of Sleipnir creature character. I did him on 7h car drive a while time ago. I hate long car drives, so much of headache...

Original sketch is for sale, 35eur.

PS: Please don't preach to me that Sleipnir should have the measures correctly according Mythology's description; it's my own way of creating him for my own purposes than... reconstructing the mythologic characters, huh??
