A beautiful dart frog

This is a peacock dart frog native to a small area in northern Brazil. I photographed it with a ring flash and one extension tube on a 50mm macro lens. The frog is about an inch and a half long which is why I needed the extension tube. It allowed me to fill the frame with the subject. My settings were 1/125, f/18, and 800 ISO. The reflection of the ring flash in the eye -- a double light crescent -- didn't look good at all, so I cloned it out. The problem, though, was the eye looked lifeless because it was a large orb of solid black. So, I selected the natural reflection in the eye of a toucan I'd photographed in Peru from close range and pasted that into the frog's eye. I think that improved this image.
