Gravelleaf Reference (lazily done)

Yeah I am tired but I figured it needed to be done :/ especially if I want more people to draw her for me. But oh well, as I said done lazily cause I am tired so don't think too hard on how bad it is XD
gravelleaf.deviantart.com/gall… - Other examples of when I drew her.
*Edit is adding profile*
*New edit 11/4/16 lightened blue and added a little more info*

-Some more that I am wanting to say on this as I have seen and heard about other characters and basic things like Gravel's eye color. I did not make them like that to be different or unique, I made them that way because I have always had a fascination for heterochromia. That is all I can think that needs to be mentioned at the moment. If anyone has any questions about anything or would like me to clarify something let me know.-

Name: Gravel
Gender: Female
Age: 18
Species: Winged cat/ Human
Elements: Electricity/Darkness
Personality: Serious, Caring, Stubborn 
Size: Medium-small (size chart - Size chart wip )

Fur color/Odd coloring in general explained -
The animals that have a certain color or two on their bodies that are not natural are symbols of their element. There is no specific color for each element, i.e electricity can be blue, yellow, or any other color electricity appears in. Cats have a typical fur tuft and end of tail that is colored, but it doesn't have to be. I will add more refs later, which will show the variations. Gravel's colors of an aqua-like blue fur for electricity, black/dark gray fur is for dark. Her eyes are two different colors because of her electricity, her eyes used to be just blue, but when she gained her elemental powers her right eye changed to yellow. Her source of electricity is her front left paw mainly and tail. Souce of darkness is her front right paw only.

Story (sort of, please forgive my bad writing skills) - 
    Gravel was born as a human in a normal society like ours, but one day everything changed when she was kidnapped, at the age of 16. She was taken to a lab where many people of different ages were being tested on and injected with strange things. She was in an observation cell for two weeks before it was her turn to be used. 
    The day she changed, and was no longer considered "normal" was a day she will never forget. The pain in her back from the long needle, the burning and pulsing. She was brought to a cushioned room, where her hell really began. Within 24 hours she had completely changed, she was now a cat! Not only that but she had wings. She panicked, how was she going to live her life as a cat now? Why did they change her into something like this?
    For the next year she was trained in the art of fighting with this new body. Eventually she was able to switch between cat and human at will. What did she see during this time? Death and pain. She was only one of the hundreds of test subjects, but she was one of the few who survived. If you were lucky enough to survive the transformation you were quickly sent to start massive training. She was forced to fight and kill other test subjects in order to survive herself. 
One day she and many others were given their chance to escape, and they took it. An experiment had gone terribly wrong, they created an explosion so huge it destroyed much of the place. In the confusion they were able to escape. Into the woods they ran, as far away as they could. 

After the escape many of the creatures grouped together to be safe, and to stay away from the human race. Many of them also changed their names. What would happen to them if they were discovered? They hoped they would never find out. Gravelleaf became the leader of one of these groups, and not entirely by choice. They decided to follow her and soon they had built a small village and were happily living. Until a rival group showed up and threatened their lives.

Not gonna say anymore on the story in case I actually decide to write it, but it all depends. This is not based on anything. Just one of my imaginations where things happen and stuff.

So yeah, I hope you have a better idea of who Gravelleaf is now XD Human ref will be up soon, as well as some of the other characters.
