Greetings from the Critique Club. I have studied your entry and have some thoughts on it. First off you have met the challenge technically real well. Your photo definately shows a shallow DOF, well done. I voted this photo a 6 during the challenge.
A few points that might help you bring the score up for the next challenge. The main image is lacking the pinpoint type of focus on the main object that seems to be required to score well here on DPC. Your main subject is also a little dark. I would recommend playing with different lighting to help that out. The background while blurred is still a bit busy. Try and get the composition of your photo how you like it, and then step back and look at the background and see if you can get the view you like with a background that adds to your entry. And the last note is to try and remember to always use the maximum allowable size of 640 for the longest side of your entry. This alone would have brought up your score in my opinion. Well done and good luck with future entries.
technically, you got the job done, but compositionally/visually, it's a bit too busy. love the colors. hope you can get back out there and try a shot that is similar, but without as much going on.
2 - Good potential. Criticism; 640, in this case height. Perhaps not as tight a crop on the top, dependent of course 'what' is there, would have made this better in my opinion. Nice colors and composition and DOF, as far as I can discern. More detail in the seedheads/textures too, but that may be there at a bigger size so who knows.
