1) I like the composition - but the PP seems a bit excessive? Kinda gives a hazy feel, the framing is good
3) Looks good, this is my favorite. However, the white light reflection in the water looks like someone whited it out, it's even stronger than the actual light
4) Great composition, you could even see little stars if you look close enough, interesting angle too.
5) Also nicely composed, the blurred figure in the background makes it more thoughtful
Anyways tha'ts my 2 cents =P for whatever its worth, great pics tho!
