Panos using Photomerge

I was playing around with Photomerge yesterday to see how it worked, using 3 panos that I had [very] manually created in the past, including this 3 shot pano from Kaikoura [click for larger images]:
I converted this to mono as the original was even more boring with a heavy blue cast.
and this one taken on Boxing Day last year at the McGee (about 7 shots):
I did have an 18 shot pano of Sydney harbour at night, but it didn't save for some reason.
Overall, I found the Photomerge application quite good and time saving. I notice changes in exposure are quite distinct, but can probably be managed quite well when one has the inclination
C&C appreciated.
