I very much like the foil of the horizontals behind the bud vase. If it was mine, I might have moved the vase to the left and get rid of that dark area to the right edge. But it is a great concept, nicely photographed and the light through the rose is spectacular.
Excellent shot, ligthing is very good. I like this one a lot. The only thing that I might have done would have been to straighten the pic to where the vase stem and that line light/dark (wall behind the blind on right) were Straight up and down (perpendicular to the bottom edge of photo). The shadows would retain the effect (perspective) and the vase would not appear to fall over at any moment. Nice work.
