Magnus turns Lestat

So, I've been drawing this a while ago but I didn't know how to finish It ( background or not, paper texture or not, colors or not...you got it) and then I just drop it.
But thanks to my best friend Camillou who kiked my ass and told me that I should post it and stop being so captious, I finally did...

Its the scene in "the vampire Lestat" when Lestat got turned by this old (and crazy) vampire Magnus
So the characters belong to Anne Rice in his vampire chronicles.
