Great photo, Milan but you need to post both your camera specs and your pp techniques - at least the basics - so we can comment effectively. If you have questions about what to post you can PM me or read the guidelines at the top of the forum. Thanks!
Very nice image overall. I'd love to know what camera/lens you used. You got really nice detail in the frog and a beautiful background (BG) to go with it. Nice diagonal composition as well.
Tree frogs can be extremely photogenic and this one is no exception. An interesting perspective - looking up at the frog. Nice view of the pads at the end of the toes. Good sharpness, comp, lighting, background, and pose - though I think the image would be even stronger if the head was turned a bit downward toward the camera. Well done.
Sorry, here are the rest of the data:
Canon 40D + Canon 100m macro lens, ISO400, f8, 1/250, -0.3,
Just basic PP: fixed levels, add a little colours and contrast, sharpness, no crop.
