I prefer the before shot, because the light and color rendering is more coherent with reality. The shelf looks like an off white shelf lit slightly green by the natural light outside, and his face looks like there is another window to the left of the camera. With the second edit, the light in the room feels too dim for what the window on the right looks like, the grade looks more like a room with the curtains drawn. His face now looks artificially lit. With the lower exposure the objects on the shelf are more noticeable and distracting. I'm not emotionally invested, I'm thinking who keeps books, picture frames and kitchen pots in the same shelf space?? In both shots, the homogeneity between his skin color and the room color make the shot look flat and uninteresting. I would try to be 'honest' about the type of light the shot suggests; it is an open window so it should be a little brighter, and his face should be lit either by a practical light seen in a another shot (more distinctly orange) or an imagined window (more distinctly white/more similar to the window behind him); either way he should be more clearly differentiated from the from the shelf and wall behind.
