Hello, my name is PervyPanda. I am writing to inform you I have taken liberty to use this picture (one of Severus Snape) as the cover image for my Fanfiction on Fanfiction.net. I have and will continue to credit you as the owner and creator of the art for each chapter this image is in use. I fanatically hope you don't disapprove, but if you do I will take the image down immediately.
My Fic (I hope this doesn't count as advertisement) Is called "Can I Really use Hair Grease as Potion Ingredients?".
I deeply apologise if this offends you in anyway.
PS. Formal speach is irritating as hell to write, you need not respond in this manner.
PPS. I love the drawing.
