Wow
Pros
The focus on the flower is beautiful.
Tonal qualities in the photograph are wonderful and attribute the mood of the overall piece.
The overall mood of the photograph to me is remembrance. It's like there is something about this flower that is supposed to trigger a memory of some sort.
The lines created by the pedals create movement of the viewers eye. It pulls the viewers eye into the middle of the flower and then back out.
The lighting is beautiful on the pedals. It's as if the pedals are sparkling.
The photograph almost makes the viewer think about what is the memory or emotion that is triggered by this flower.

Cons
The only thing i would say is that the pedals farthest away from the front are a bit out of focus.

Overall
Wonderful Photograph. I would put that in your portfolio! Great Job.
