Great photographs! Great use of the colors and nice shutter drag. I feel you nailed it for the fountains in 1 and 6 however #2 could have used a longer exposure, but that because I personally like the continuous lines of the cars passing through. Great locations all. I love Casino shots. They are always a gamble to get lol. They do frown upon pictures taken in the Casino.
For the second shot...I would have loved to have a little longer and to get the red blur lines as well but it was trafficky and they were not going anywhere. Typical thing about photography...the subjects won't always cooperate.
