I'd love to visit this museum some day. The American Museum of Natural History (in New York) is another great one (in terms of content), and a place where I spent countless boyhood hours.
Very nice use of the fisheye. Is that Canon's 15mm, on a full-frame sensor, or perhaps an 8mm on an APS-C sensor?
Great Shot
One suggestion - take this into Photoshop and ensure it is straight. Seems to be leaning a little to the right (using the center line on the roof to judge)
Good work
