@Braden-Hallett haha wow didn't see this concept coming good job.
I was thinking that the expression of the old lady could be more intense? Maybe she is angry and surprised at the same time? (like what the F i just heard?!) kind of puzzled look as she is thinking about it? I picture that she wouldn't have a clear looking direction in this situation (like when you focus your hearing to a sound you cant see - you will have a blank look)
I figure that this might hurt your composition tho so its up to you, but you can try it maybe idk.
