#1 is my favourite, I like the lighting on the flower. Nice pastel out of focus background
#2 is good
#3 is my next favourite, I was a bit concerned about the flower head being high in the frame, but I think the stalks as subjects are interesting too. I like the doughnut shaped water drops
#4 great glow on the flower
#5 Good, the out of focus flower at the bottom is a bit of a distraction
Nice shots. The first one is the best IMHO. Great composition and clean colour combination.
The last one for instance suffers from the blurred flower in the foreground unluckily of the same colour as the focused one so it catches eyes in a distracting way. This does not work for me.
