Very cool idea but I think if there was some way to make the flowers appear vertically in the frame instead of straight out at the camera it would have worked better.
Loving the flowers, the angle you shot at and I like the idea of the frame alot BUT its not 100% straight and that is bothering SO much! I also think that if you cropped enough, so just the frame is visible and not so much space around it...
If you had set the frame on somethng raise it a little, it would have been in a little more focus than the background and been a little more pleasing to my eye.
