Brilliant colors...the image hardly looks real. Very nice composition and a lovely curved stem for a perch. A slightly different angle showing the tip of the abdomen would be nice. However the colors really make this image stand out.
I like the composition and the colours in the image, the soft background is also very good. I have slight reservation over the head - is it quite in focus/has it been sharpened enough?
Nice subject, composition, color, pose and background. It's interesting how some elements are so sharp -- the tiny hairs on the legs are quite pronounced. But it would have been even better if you had stopped your lens down more, to increase DOF.
