I can only adhere to all the positive comments above; I really enjoyed your galleries.
I was in a big hurry so cleaned the sensor using only a long shutter speed rather than the cleaning utility, which was followed by a test shot to check the progress of a particularly stubborn spot. Forgot to reset the 30-sec shutter speed, and it closed on the swab...hard. Totally destroyed the trailing shutter blades. It was a stupid and costly mistake. When my wife found out it cost $600 to repair, I almost didn't survive.

Ouch! That almost happened to me once: did the cleaning with a 30s shutter speed, thinking I was in the cleaning mode (fortunately, it did not take me more than 30s, or I would have an expensive paperweight by now).
