Very nice tones and lighting. Background in the upper left is a bit distracting, and I personally would have preferred more space at the top and bottom.
The tulips are beautiful and beautifully lite. The focus is good. The background is distracting. Either a solid white background or a much closer crop would have upped your score IMO.
It seems a little dark in the picture. The black and white would work well though, I love the shadows cast by the inner petals. Also, there's some distracting backround elements, but overall a good picture.
