Thanks for commenting on my work! I think you are right, its over sharpened a little. I noticed these boys in the park. They were sitting and smoking on the banches of this tree))) Then I noticed that their faces and hands were dirty... "Street boys"
Yeah, agree with Cleveland Smith about the over sharpened bits around the tree, they _are_ rather distracting. Apart from that, I really like this image and the natural feeling of it; what IS a bit distracting though is that the background is lighter than their faces and draws therefore quite a lot of attention.
Olga, good job with this image, good composition, love the face on the middle boy, however, on my screen, there is a lot of fractualization, around the boys upper bodies and also the limbs of the tree, could be over sharpened, I don't know. You still have a good image, just my ideas and opinions.
