It's really unfortunate that a lot of photographers don't bother to fill in the "Photographer's Comments" section when they submit a photo to a challenge... especially when they check the box to request an in-depth critique. I have stopped offering in-depth critique on photos when the photographer chooses not to include his/her own thoughts on the image when they submit it... You might want to consider this in the future.
The backgroud flowers are distracting from the subject by seemingly growing directly out of it. In my opinion, this could be stronger shot at a different angle.
I've seen a lot of plants and trees... Yes, they meet the challenge, but where is the creativity... It's the image that stands out from the rest that wins me over.
