Hong Kong Night Shots

This series photos was taken from two different days one taken between 7pm to 8pm without tripod. The other day taken between 8pm to 10pm with tripod. I like the first set of photos, the blue sky really nice and the contrast is good also, all shots are taken with below 1 second shuttle speed. On the late night, the background light is too bright, when I use more then 2 seconds shuttle speed, the picture is too bright.
