Positives - well photographed, lovely light, good depth of field, with the poppy, and particularly the bud standing out well.
Negatives - for me, at least, cerise and red are not a good combination, with the cerise geranium adding a rather garish feel. I also find my eye following the 'gaze of the poppy' and drawn out of the photo.
your harsh sun is working against you...me...I would have loved just seeing only the face of the poppy with the stems in the background like you have them...the phlox (??) at the bottom of this is a distraction to ME.
I really like the composition of this image. At first I thought that the colors of the different flowers were clashing too much but now I realize that I like the contrast, and how much they bring each other out.
