Remember my unigirl, Sammy ( http://www.furaffinity.net/full/3067195/ ) ? When I said "Expect to see more of her soon !" I actually meant "Expect to see more of her one day..." XD Anyway, here it is. I changed a bit her design, nothing really important.

Sammy's a unicorn, and she's candy-colored, but don't be fooled : the most poisonous mushrooms are often the prettiest. Scientist at heart, she use dark magic as a mean to satisfy her consuming curiosity. Curiosity kills the cat, you say ? Well, she did kill a lot of those. And a lot of other critters. Heh. You need a lot of drafts before actually making a masterpiece. After all, no one ever said that the path to immortality was easy. Unicorns have very long life spans but they aren't eternal. Sammy wants to change that. But when you play too much with fire, you might burn yourself. And she did : her hands are cursed. Cold as stone, unhealthily purple-ish, they are so bony that they seems to be a corpse's. She hide them in her sleeves, only showing them to her guinea pigs. Not like they will tell anyone, anyway.

On this picture, you can see Sammy's fullbody, her feral appearance (the decaying horse-banshee-thing), her right arm markings, and a silly doodle showing that Sammy really hates her breed and thinks that most other unicorns are retarded...
