Fish on the book

I figure that I'll keep the fisheye on the camera for a while yet. Normally I would use a 50mm prime at about f2 for a shot like this (indoor, available light, portrait) keeping the fisheye on the camera is forcing me to see things fresh. In this shot, I like the way that the fisheye has made the book completely fill the foreground and provide some interesting 'leading lines' to the main subject. Can't do that with a 50mm.
