The reddish tone of the background in the top right and the faint vertical lines on the wall are rather distracting. If the backdrop were more uniformly red the white of the flowers would stand out a lot more. As it is the flowers don't stand out too much; using a shallower DoF or misting them with water would help to make them feel more three-dimensional.
Good potential, I like the crop. But the lines in the background are distracting. Also there seems to be a lot of noise in the shot along with some jpeg jaggies on the diagonals. Probably suffered a bit from the compression/resize.
