Already, 2 comments and I'm thinking clearer about the image. Thank you eland, and Leighow!
I think there is too much of the out-of-focus green leaf in the foreground. I might crop it tighter along the lines eland suggests.
Also, I think the image is confused--it would work really well as a study in color and lines *without* the butterfly wing, but the wing is such a distraction to that particular image.
I also find the bright element distracting. I might PS it out just to see what happens.
Unfortunately this is pretty much full frame, so there's not too much to play with. I'll mess with it, and re-post the result, just for fun!
thanks again!
