I like #2 - it's a nice concept - pose, background. Light is very appealing.
#1 and #3 as well
#4 Doesn't match the others though. Not very flattering light and scenery...
#2 is my favorite one (the background and colors in photos looked good). I think #4 & #5 had distractions in the background that kinda took away from the picture.
#2 is my fav...love how they are all so tack sharp!
I love #2! Such a great shot.
