This is a new angle for images of this sort, normally shot symmetrically (I'm kinda ambivalent to it). Focus appears sharpest in the ceiling, but is too dark there to really discern detail well, and where light is shining adequately detail is a bit soft. (Or are my eyes playing tricks on me at 3 in the morning?) Also, is the glass really that purple, or does your lens suffer from really bad chromatic aberration? I'm guessing the former since the rafters appear to be bathed in purple light. Valiant attempt in difficult lighting circumstances.
