This is nice first post but I do note much "noise" in your shot particularly the sky. You might try tightening your focus and also using an editing program like "Neat Image", which is free, to clean it up a bit. Welcome to Ceaedes and I look forward to more of your work.
Quite a sight. I can imagine how awesome it looked from your vantage point. Tough to get the city lights in sharp focus in low-light conditions with a hand-held shot, but a good attempt nonetheless.
I have never seen Paris but if it looks like this photo it is gorgeous. As Trixxie mentioned just a few little touch ups will add to this photo. Thanks for sharing.
