Thank you Dan and Thomas for the comments
I updated the thread with a few more images. Most of them were taken on a tripod at night:
Pont Alexandre III
Blue Eiffel Tower for French EU Presidency
View from the balcony of the student residence I live in
I submitted this image to the August assignment. I like it despite the fact that I didn't even get one single vote :p
Hope you like them! C&C are always welcome of course!
PS: I've no idea what happened to the 3rd image in the original post. Maybe it's because I modified my gallery.. Now I can't remember what image it was...
