Beautiful picture, takes you away from everyday problems and you remember when you used to play on the similar tree. Great moment, what a joy, and nicely composed too. Colors are gorgeous also.
There is one little problem regarding the quality but I’m afraid to say anything since it seams that I’m the only one who sees it. I believe that you had to resize this photo from the original size and then I also believe that in this process something didn’t work out well. You can see that on the face of the boy with red baseball hat and their bodies, quality degraded due to (I guess) incorrect processing.
Please take this as friendly question not personally, remember that I really like your work.
I had a similar problem more then often, sometimes I still have this problem and I don’t know how to fix it yet. It has to do something with compression of the file, Adobe RGB and sRGB, I guess that on this site your pictures should be posted as Adobe RGB. Well, what do I know?
