Well, she's obviously a vampire. With winter flowers and plants on her head. (That's where the winter part came from) It seemed like a good idea because it's winter now and all. Well, it's deffinitly not winter in my country... (it's summer all year long! )
I used winter plants as references, such as: Roses, lilies, poinsettia, winterberries, & God knows what.
Now about the tattoo on her back: It wasn't in my intensions to draw it, but my 4 year-old brother added some blue touches of his own, and I couldn't erase them all, so I drew over them. The tattoo is a "Vampire" symbol. I saw it in TVD season 3 episode 8, where they entered a cave and saw ancient drawings on the cave's walls. The fangs are obvious, but the sun represents the vampires' sensitivity to it.
