Great shots! In the nature of FYI, are you aware that the light display on the Eiffel Tower is copyrighted and supposedly cannot be photographed and published in any manner including on a web site without permission of the City of Paris? French law has always been somewhat bizarre and I would not be inclined to take it seriously, but perhaps some research is in order. skieur
Great photos. I have a feeling #1 and #3 could be improved slightly by reducing the exposure...highlights are looking a tad blown-out. What do you think? Another thing: just a suggestion...if you want to put your copyright on the images, you may be better off putting it in a less obtrusive, but more complex area of the picture...makes it less disturbing to the viewer, and more difficult to remove.
I like the second. It is a bit of a different take, not something seen often. And deanimator is, of course, right about the sig in your pics: if I wanted to steal them from you, one stroke with the clone tool and it'd be gone from an all black sky or an all uni-coloured part of the photo. Plus it is really distracting, large and bright as it is on the dark background.
