Hi Kostas. The butterfly gave you a nice pose and the flower is very colorful. The background is pleasingly blurred. You might try a little more selective sharpening on the head and body of the butterfly and I would suggest cloning the brown spot in the LLC. Overall, this is well done.
Hi Kostas, you captured a good pose and did a good job with the flash. In addition to what has already been suggested, you might consider brightening up and sharpening the eye. Also the colorful areas on the butterfly look a bit flat so try selecting the upper parts of the wings and increasing the contrast on just those areas. A few tweaks should take this one up a notch or 2.
