I found this composition a bit odd. I couldn't quite figure out what the foil wrapped thing was at the left. It is an obvious light source but I don't think it enhances this photo.
I like the lighting effect, but I'm not sure I like the rotation. I turned my laptop on it's side, and it seemed to me to be better verticle. it's got a weird 1950's pre-fab starry sky thing going on.
Your aluminum foil cookie casts a lovely light on the flowesr, but I think I would like the picture better with it cropped out. The sharp contrast on the foil upstages the soft moodiness of the flowers. 7
