In the bottom right of the picture, if you look at the hair on either side of the hand, they are different. The girl’s hair is black, the hair below the hand is reddish brown. So, you’re right, there is a fourth person barely in the picture.
Having said that, that makes his arm with the watch and the tattoo his right arm. So, at this point let’s just agree to disagree.
And, I would never laugh at your artwork, unless you meant it to be funny.

We both know that mirror is mirroring image. Right becomes left and left becomes right in the reflection.
If we look out of Ken’s eyes, then he has his right hand raised in a fist. But in the mirror, if you look outwards from the perspective of the mirror, that hand is the “left” hand.
Which means that I should have said above that his right hand with the phone in it is not visible when looking from the perspective of the person in the mirror. From the point of view of us observers, this hidden hand is actually the left hand.
I have used the perspective from the mirror towards the persons to make it easier to draw the picture with my hand.
I can also try to draw the actual state of the hand from the person’s perspective, but I’m a bit embarrassed about the art of drawing with a mouse in paint
Yes, whether we look at it from Ken’s (our) POV or from the mirror’s perspective, the arm we see in the mirror and in the picture is still his right arm.
BTW, I thought your second drawing was better than your first.

Why do mirrors reverse things left to right, but not up-down?
Here’s what science has to say:
So mirrors don’t reverse things left to right. Mirrors don’t actually reverse anything. It’s you who are doing the flipping.
Think about how a mirror works. Photons — particles of light — stream toward the smooth pane of glass and bounce off it. The image of everything in front of the mirror is reflected backward, retracing the path it traveled to get there. Nothing is switching left to right or up-down. Instead, it’s being inverted front to back.
