I love this artwork and how you drew the patronus! It is amazing!
(I do see your points of view, but Lily in my opinion is a sweet, strong, and selfless woman...I mean she offered to die so that her son/harry could live. But I do agree that running off with people who embarressed severus, wasn't the best choice...)
Anyways, you drew Snape's nose perfectly and as soon as I am done commenting, this is going into my favourites!
