Nova - Character design - Reference Sheet

My newest Dragon character!
"Meet Nova, the lonely dragon. She is still very young, in past she was attacked along with her friend by agressive pack of dragons. When trying protect her friend as a stronger one, she lost her wings - other dragon just bitten off her wings. Then they kill her friend. World of dragons wasn't the safest place to live, never and since then she know that too well. She somehow survive, but after that horrible accident, she avoid being attached to anyone - just to not let feel the same pain again.
But her powers, uniqe for her race, start to grow. She still don't have whole control at magic she possess. She met another dragon who befriend her somehow and she let him help her with her growing powers."
