Love it. Nice subtle light and the fade off of the bottom frame is sweet. I like that small splash of light in the upper right to give it some depth. Well done!
I never have a chance to photograph these but what a lovely bloom
For me .... clean up the yellow flower as IMO it has a heavy cast of the greens and perhaps give it a bit more light for it to say 'I am the star of this show'. Just a little 'flat' overall perhaps.
The composition is wonderful Paul!
