1. The chandelier is way too small for the room's volume. If possible, your room requires three tiers .https://gallery67.com/products/wrought-iron-vintage-barn-metal-axis-3-tier-chandelier-chandeliers-industrial-urban-loft-rustic-lighting-w-60
2. The crystal just fades into nothing. IMO the chandelier should have a metal finish
3. Get rid of the tablecloth. Get a clear plastic cover if you want protection for the table. Let the wood color see through the plastic
4. The art is mounted too high and I would have selected something other than gray.
5. I have added drapery panels that match the pattern color in your rug.
6. There are sources on AMAZON that offer tall panels at reasonable prices.
7. The panels do not have to move. They can be a bit sheer and they just need to hang there because the room has NO TEXTURE!!!!

You could select an asymmetrical chandelier like the one below. It would be like a sculpture in the room.

Also place note the sheer drapery panels on the windows.

Maybe even painting that window wall would end up being a good solution.
