I like the subtle blue tones in the background..unfortunately, the barbed wire which is essential to your theme, is all but invisible at the top of the picture and only the middle strand stands out.. this serves to cut the image in half which spoils the composition slightly for me.
I think the picture might be strong enough to stand it though.. the white flowers and lovely green and blue tones in the shallow dof background are superb.
Bumping this from 7 to 8
I love the rich blues in the top of the image and the greens in the bottom. You've got a perfect depth of field in here which makes for a complimentary but not distracting backdrop. Great work!
I like the Blue and the green halves of the photo and how they pick up on the horizontal lines of the barbed wire. With the narrow focus these things make a nice environment for the delicate flowers whose whiteness and sharpness makes them pop out of the picture. Nie title as well.
