Albert I like the image very much indeed, and I think it is almost certainly high quality. I strongly suspect the jpeg on the screen is suffering a little bit. Is it a little over sharpened or is it the compression regime used to produce the jpeg?
There a couple of dust spots, one bottom left and there is one to the left of the forelegs.
Very nice capture of the butterfly parallel to the camera and lovely composition with the butterfly perched on the tip of the leaf and the bkgd soft & muted! I especially like the detail of those 2 small streamers on the back edge of the wings. If you are inclined, you might consider doing a bit of clean-up of that white splotch on the leaf, just behind the legs.
Hi Albert and welcome to the Macro forum! (Please remember to include your shooting specs as that will help us to offer more meaningful critiques. ) This is a strong image with a nicely posed butterfly against a pleasing background. Jon and Nancy have already mentioned the minor points that I was going to raise so I won't repeat. I think this image is worth a few tweaks that will make it even better. I hope to see more of your work here in Macro!
