Honestly (but don't take it wrong) I don't like the composition. I think the purple and white orchids are 'fighting for attention' with what I believe is your main topic (?). Also the green flower on the bottom left side doesn't work for me.
Hope this helps !?
I have to agree with Tinker - the image has lovely tonal qualities - the Phase 1 shines on the 'blade - but the composition needs tweaking.
Don't dispair - flowers are of the hardest objects to photograph adequately.
