@Rashed: thanks @Carlen: I could have easily fix that in PS but that's not what i wanted. There were windows on the left and i wanted the right side to stay darker, just as in reality. thx anyway.
Lots to look at in this photograph. I like the textures of everything, the wall, the floor, and the lighting into the doorway. It makes me wonder what's beyond the wall. The right side of the wall is a little dark (at least on my monitor), I'm not sure if you could fix that in photoshop but other than that this is a great picture.
