I agree with this, the butterfly should have been completely focused. If you would have opened the aperature up to like 1:16+ and focused to the butterfly only, the background would have been a little bit cleaner and clearer so you can tell what the flowers are, but yet blurred enough to bring direct attention to the buttefly.
EDIT: Keep in mind that I'm not a photography pro.. this is just what I think..
i would have liked at least the body of the BF to be in focus more....
also..there seems to be alot of little black spots. i dunno if its dust on the film when the shot was taken, or if thats how it was scanned in, but it is annoying
I like the composition with the butterfly on the right and not having anything really interfering with it. I also like how the frame is balanced with the flowers in the middle and the left side.
But technically, I feel you missed the spot to focus - the butterfly.
Another technical suggestion I have...I feel the use of a circular polarizer would have benefited you with controlling the exposure of the sky.
And a technical inquiry...which medium telephoto lens did you use for this shot? The airy-spacey feel created by this perspective fits the photo well. Though with a good angle a wide angle lens could also provide a pleasing view.
I shot this with the N50 so it probably autofocused on the tip of the flower the butterfly is on, all in all though its a very pleasing picture when put about 5-8 feet away because the butterfly almost comes into focus.
