The low white ceiling bugs me. She should go and paint it black as well. Proper bat cave.
To the rest, you wrote: Yes, the room is unbalanced, and the dead leafs makes it just worse.
The tv over the fire place is suboptimal. I know they want the fire the focal point of the room, but I would change it up. Maybe place the sofas in an L-shape, with a little table and lamp in between them and the TV where the bloody LV-trunk is. The LV-trunk, where the useless telescope stands. The two chairs where Ali's sofa is. A lengthy mirror above them (on the empty wall). Would reflect light coming from the windows and the fireplace, depending on the angle you are sitting.
Or switch it, same arrangement, but the L-shape against the wall and the chairs against the windows. TV where telescope is, LV-trunk stays where it is now.
I much prefer their sitting area in the downstairs "club" room. So spacious.
Telescope can go into the
TV-set office of Ali.
