tried this a number of times myself and yet to get it right. This is very well done although I would have moved the seed head in the Bg out of the way and try to isolate the 'separation'. Deserves to be highly placed.
very elegant and crisp. i feel that this portrays separation well. The colors are and lines are pleasant to look at. I am not sure if I like the flower in the background however. But this is still a strong and enjoyable image. Keep up the nice work.
I have a weak spot for dandelions as they are always beautiful subjects to photograph. The colors work very well and the theme meets the challenge. I am a bit hung up on the DOF but otherwise, I like it. Good luck.
