I most definitely agree with Aiman. This is such a nice image. I think the element of the story telling is far stronger here. The face of that old gentleman is a story unto itself. Wonderful work.
this is better IMO Asis.... as the previos posted one, they both carry the most hard thing in photography, "story telling"... can see that at the very first moment you look at the photo.... great work.
If you developed this photo your self, you can bring out some details in the light parts... looks burnt a little bit for me... suggest also cropping the far left kid (nothing persnal against him)... just to end the composition, with the direction of the teacher's hand, towards the young boy, who is looking at him... closing the eye navigation circut in the frame...
