Hey Stuart,
This one too looks a touch bright and yellow.....so somilar to other post.....I would tone that down. The flash opened up the BF nicely but I would tone down the FG leaf a bit more than the rest as well. Nice pose and the minor tweaks should take this up a notch.
I agree with Roman but I really like the contrast in color of the butterfly with the plants and I like the placement of the butterfly in the frame and how it is posing.
Stuart...nice capture of this bfly ...I like the pose and sharpness on the bfly. I would like to see the bg simplified by getting rid of some of the black holes or using a more open aperture next time
Very eye catching and a difficult image to control. I would suggest bringing everything down a little, the highlights, the contrast and the saturation, I think you have a fine image. Maybe of course you prefer the bright colours but for my eye and monitor just a little on the heavy side.
