Um, I have no idea how many hours or days took this picture. But it was super fun from the very first sketch to lest details! Even it's not cup of my tea I loved Steelius's vision, idea with colors and last but not least his agreement and patience!
Whole monster picture belongs to Steelus from Deviantart.
