Vampires
As they grow older their nails grow yellow and light red but they cannot cut them or the blood will flow and they will die
The older they get the more transparent their skin becomes the more prominent the veins become this one is only a few hundred years old they have green venom to kill their victims ( its hard to see in this picture but it is there)
This is the fire princess who died years ago when the vampires attacked her village and she was the only survivor the only one who didn't succumb to the venom and instead embraced it and turned.
This took me an hour and i am very proud of it because i turned out really well and its really good for my skill level
