Here's your Critique and Feedback, as requested! :D
This is by far one of the strangest photos on DPC this week. Based on the original image you posted in the description, this is only a small portion of the image of a cigarette you took with your camera. Overall, it's a fantastically composed shot, but since you cropped in so tightly from the original shot, you get quite a bit of motion blurring on the embers of the cigarette.The original shot appears to be all in focus, but as you look deeper, the only hing that's truly in focus is the spark. The more of the full-focus spark you can show, the more my interest grows on this photo. This can be fixed by using a stronger macro lens or a reverse-lens technique so you don't have to crop-in so much, exposing the blurry elements of the cigarette embers. Also, there are many different ways you couldn't cropped this. And I personally feel showing a bit of black above the top of the cigarette and off to the right a bit would've raised your score, and still not have exactly exposed your "Puzzle." I like the blurry sparks in the background as well, and I'd like to see a crop where you showed the entire spark as well as the cigarette ember, but without showing anything more on the bottom-left of the cigarette itself. There is a lot of interest in what you've copped out and I'd really like to see some of the in the photo. You should aim to show as much of the photo as possible without exposing its true form. I think you would've gotten a much higher score had you used a stronger macro lens and not cropped out the entire spark. overall, the effect comes off as almost lighting. I like it and I think I gave it a 5 or a 6 in voting. This definitely deserved a higher score then it got. Hope I helped!
