Wow, this is fantastic; I love this part of Portland as everyone seems to be so friendly, and the view is amazing when the Willamette isn't clouded with muck. I've never seen it at night time in real life but I'm sure this photo does it justice. :]
this is really nicely composed with the natural part in the foreground which is darker and then the blazing lights of the city in the background. so many little details have been captured it;s a pleasure to look at.
Thank you I did use a polarizer, but I found that once I started playing around with the white balance, my photos no longer had a yellow overcast (half of the photos I took that night looked similar to the colors in your photo). I also brought out some of the shadowed details with curves to create an image with more dynamic range
