Yes it the first one for me also, as the contrast of colours across the shot, is just so pleasing to look at and work so well together - excellent.
And (this is not a nitpick btw) but I would be sorely tempted to clone a flower in behind the butterfly on the left to fill that gap, but that might be a cheat too far to keep it "real" for you, but none the less, I would still have to do it to see what it looked like, with another flower or two filling that area of the shot.
Great shot.
