The flower is nice and I like the detail that you have in the petals, but, I agree with IzzieK, the background sort of kills the shot. When I shoot flowers I try to shoot against a background that is a complimentary colour, in this case it would a shade of yellow, or I would try and take the background out of focus as much as possible, so that little if any detail can be seen in the background.

What aperture did you shoot with?
