this is so pretty .. and the colours make it exciting too .. i find the background pleasing even tho i usually like it more out of focus .. i think because the flower in focus seems to be emerging out of the crowd sorta .. !! .. if the background was more in focus it would lose that feeling for me .. :)
DOF is a tough one with a macro lens, at least that's what I'm discovering recently. That being said I do like some nice bokeh. :-) Might be a tad shallow, but not much. Like the flowers too. :-)
I really like the color range ... I agree that it would have been great if that top leaf(?) sticking up had been in the focal plane -- the rest of the blur looks fine to me
