Well, the first I see is that he is relatively sharp. Which is quite something in a Rob91-photo, isn't it?I also immediately see that his face is too dark. Many bright elements in the blurred background are pulling one's eyes, so that the feeling "hospital ward" is becoming an overwhelming one, but there is no light in his eyes at all, and too little light on his face. His neck and back of his head got lit from somewhere but not his face. And I feel that is where there should be some light.
I hope nothing's wrong with your grandma! He looks like he's waiting outside someone's (his wife's???) hospital room.
