I really love this one! *__* Sirius' faceee! I love how cheerful he looks (given that he wasn't very cheerful in general at the time). Also the background! Your ideas and designs for it are very fitting and atmospheric - the serpents on the plates up there especially is a really nice touch.
This literally made me grin. I love this, & their expressions (especially Sirius'!), & how Harry is just a head. Maybe i'm just easily amused ahah. The detail is amazing, too; there's such a sense of place that makes it feel even more realistic.
