I've never entered one of Deviantart's contests before. But I really LOVED this one, I had an art activity book when I was younger and it has a couple pages of the scribble game. It's also pretty fun to play with friends, try it if you haven't.
The scribbles are her back spike, chest, and glowing orb.
The concept of this monster is she is an orb collector. The orb collectors are a group of nomads who go out at night to collect there very magical glowing orbs, they take them and put them in a deep underground cave because if someone with the wrong intensions collected them that person could do some magical damage.
This is scribbles a female Orb Nomad, usually the orbs are about the size of her palm. But that night she was surprised to find the biggest one any collector has ever seen! Lets hope she can take it back to the cave safely...
This was done with Markers and color pencil.
