I think the problem here is that there's not enough front lighting and rather odd backlighting, so the face is partly in shadow.

I've brightened it, Color Balanced and sharpened here a little, which brings it out slightly, but flesh tones are always going to look a bit odd with the vivid colour mix in the background and that Pub Lamp of God backlight effect.

This crop is possibly a bit sterile because it's lost the hands, but it highlights the thirds, and also removes the chairs which are a bit cluttery.

Anyway - it's a different take on the scene, so I thought I'd try it this way to see how it worked out.

Interesting blue eyes now too. (The spice...must flow...)
