beautiful James. i have a couple of suggestions if you're wanting some...
#1 i absolutely love the ground shadow. but my eyes are distracted by the top corner shadows. is it possible to either make them stand out more specifically, or to reduce them?
#2 i am always in the corner of the underdog, no idea why i am but that's just me... i wonder what this flower with the missing petal would look like as just an 'incidental' rather than the main subject. would it lose any attention, or gain some?
(your flowers make me hanker to get some blossom photos - hopefully tomorrow i'll have time and it won't be too windy).
