Nice image. Has a nice soft delicate feel to it, has some interest to it. I think the bottle could be a bit of a distraction either crop it out or add a bit more lighting on it.
It definately does meet the challenge. Nice attempt.
This doesnt look like it uses the full 640 pixels width and so seems a little small - getting it as big as is allowed can really help with the fine details. Most of the wine bottle to the right is dark for me, obscuring most of the label so much so that I find myself squinting to try and see what it says, which distracts from the flowers. They are soft, which is good, and partly I like how they are brightly illuminated, but I also partly think they are just a tad overexposed. I also wish I could see more details in the petals, but that is mostly due to the size as I mentioned earlier.
