Well it gave me some headaches around the head but I managed to get it done. Despite that, I loved the shape of the creature and the fact that it has no eyes, those was the main reasons why I had chosen go for the 3D model. Thanx!
It's not actually a concept with an interesting story. It is a twisted (and very well done!) form of a real dog who is, according to the history of the peoples of Mexico and South America, who is said to accompany the dead through the underworld. The xoloitzcuintli is a hairless dog native to Central and South America that has been around for over 3000 years. When a person died a xolo was sacrificed and buried with them because, in order to cross the underworld, they needed the xolo guide.
There is a river (or rivers, I can't remember) that must be crossed and it is said to remove the sin from one's body. Butterfly xolos (the ones with the round white spots on their legs and bellies) are said to be the xolos who chose to come back to earth and those spots are from where the sin was washed from their bodies from the river.
With all that said, it is easy to see where the inspiration for this piece came from. It is weird and creepy and looks nothing like the beautiful xoloitzcuintli but it definitely has something xolo-ish about it and it is a great piece of art!
