I like this one very much, the pose is good. I think you chose the best angle, at first I thought maybe a little more to the right would have been good but you have good DOF and I like the fact it is possible to see two wings as opposed to just one.
I do wonder however if the colours are a little too saturated.
Hi Kostas, love the composition on this one withe diagonal flower and the hanging butterfly. Agree with Jonathan - I 'm wondering if this is a little over saturated and perhaps over sharpened a little - may want to back off those a little bit and see how it looks. Also, a larger image is allowed for critiquing I believe which would help in providing comments. Overall a well done image...
Hi Kostas. This may be one of your better images! Nice light as well as good comp, sharpness, and background and the butterfly is giving you a nice pose. Very well done!
