#2 I love - the shallow DOF works for me, the colors are great, no noise, etc..
#1 has distracting bright lines in it, really hurts the image. Looks like rope or something to tie the rosebush to something for support.
#3 is ok, but the white background is meh. Also the flower in focus blends into the one behind it which it out of focus - something I always notice on my own pics only when I open it up on the computer screen.
