I picked a close up shot because you can see in depth the character emotions or feeling and it seems more realistic. for example if you have a close up picture of Sherlock when he is shocked his facial expressions show that emotion, using that photo we can deduce the particular emotion with the help of his facials parts and their shape/position. Many close ups used can tell us a lot about the characters personality also it may help tell the audience part of the scene. An example of this would be if the emotion is scared the scene may be very sinister or have a dark tone/feeling.
(P.S I had difficulty uploading a picture.)
