I like the idea, but I think there is a little too much photo around the main subject. It feels like the flower should really grab your attention, but it just doesn't quite seem to be doing that for me. Maybe a tighter crop around the three flowers would help?
I agree with Chase. A tighter crop around the three flowers would work much better IMO. Also the selective coloring doesn't really work for me. What was the original like? Why did you choose to apply the selective coloring?
