This makes an interesting abstract. The vents at the bottom are sharp, and the metal makes nice reflections, The flame is a great color blue. Perhaps a greater DOF (longer exposure, smaller apature) would put the whole burner in focus and leave the flames blurred and impressionistic. Might give more strength/impact to the image.
Oooh, this is nice. I like the hot color tones reflected in the metal rim. The DOF is fabulous. This piccy is awesome! Only, I see some spots and specks about a third of the way up from the bottom of the picture. Since the advanced editing rules are in effect for this challenge, I would defeinitely have cloned out those defects, because the rest of the image is so smooth and perfect. Probably I would also have used less JPEG compression, this is only ~50KB, you have ~150KB, make use of it. One point off for slight JPEG artifacts, one point off for spots. 8.
