Extremely effective and notable. This is one image where the flowing water meme is efficiently used. The subtle lighting, reclections and right on the edge highlights are very well done. The font and placement are almost an afterthought but work well. Well done.
Nice but I dont like the caption. I think we can all see it is at night but it would be nice to put the state where it is located to make the post card a little more complete. Nice night time cityscape tho.
Lovely exposure on the falls. A nice night shot. Not too fond of your border or choice of text/font (I am judging on that as well since this is a postcard challenge).
