lighting on left pretty harsh. use a piece of paper towel over the light source in order to diffuse the light and give it a softer effect. i also would have chosen a different background.
I'd be happier if part of at least one of the roses overlapped the black/white transition so that it was clear both were in the same original photo. I'd also be happier without the blue smoke.
I was a bit "blah" about how the white was larger than the black, and the white side's rose much sharper, but maybe you intended it that way, I don't know. Was the title supposed to be "Life & Death" perhaps? I didn't take that in to account for scoring, by the way, just curious. :)
