James actually looks like he's rather enjoying himself. After all, have you seen some of the faces men make when they come? It's like a mutant having a seizure.
This really is fantastic. Wormtail made me laugh, but in the end, he sort of detracts from the hotness of the rest of the sketch. I love the dichotomy of expressions, and how smugly nonchalant Sirius looks in comparison to James. Remus has fantastic scars, and I like that you weren't afraid to use them in abundance. I think they're part of what makes him attractive (unless we're talking about cardigan!Remus from the movies), especially when he's not ashamed of them.
