I think its around 1/5" of an inch. I thought the dead flower made it unique:). I like the range of subdued browns and greens. Unfortunetly these guys depend on salt marshes which are few and far between in my area due to development and a number of other factors.
Lovely little butterfly Chad, well exposed and sharp detail. The soft green/yellow BG is a perfect back-drop for this subject.
I think I would have included just the single leaf and Bfly though for a more simple composition.
I think the elements of this composition are all very good. But what I see here is a plant with a butterfly as opposed to a butterfly on a plant, if that makes sense. The plant dominates and the blue is secondary element. Not that that is necessarily bad. Just not what I expected.
