It's a bit sad because of too much dark but its great !

Not clear where the light on the figure is coming from. (Windows could not light his face and they would create a shadow angling away, not towards, the windows.)

IMO man's shadow is a bit sharp, comparing to wall's shadow... and needs more perspective, considering lighting source. But it's a good idea!

thank you all for your valued suggestion. I've changed some details, e.g. I added some more light to the man, I correct the sharpness of the shadow etc. But as the man is siting close to the window so the shadow will be not too much bigger, you can see the beam shadow. When I took this pic I used the same angle for the light as the window. But I changed something more for your suggestion. Thanks again. Your correction or suggestion is always a lesson to me. So please feel free to give comment.

I think this is better. I'm willing to accept light on the model's face on the side toward the viewer (opposite from the light of the window) as a necessary artistic decision, but I wish his shadow were more realistically to the right so we only see three quarters or maybe just a half of it. I don't know what the bulge shadow half-way up the right-side wall is, but I would clone it out because it's distracting.

nice mood

Ahha !! sad sad mood !! but nice work author ..

I love the mood on this, not sure about the amount of blur on the background compared to the model, yet it does make him the focal point which may have been the intention, nice entry

thank you all...
