Beautiful lighting and color! i feel it might be a bit to tight of a crop for my taste, i would have love to see a bit more black on the left, top and bottom. i think the focus is nice and the angle gives the photo a bit of depth very nice work!
Man the color really pops out of that black. Seems like you may have used some kind of special lighting. It looks great. I like that you took the "side of the flower" perspective. Its unusual, and it works for this flower.
