Thank you, I like the plates and the tapestry the most, where can I get them?

Do you suggest any other piece for the other side of the wall, to the left of the table?

The wall is so big I would do a gallery art wall. Check out this one on Houzz [https://www.houzz.com/photos/laurel-canyon-music-studio-contemporary-home-office-los-angeles-phvw-vp~15610706[(https://www.houzz.com/photos/laurel-canyon-music-studio-contemporary-home-office-los-angeles-phvw-vp~15610706).

This art wall idea is pretty cool as well: [https://www.houzz.com/photos/traditional-kids-traditional-kids-new-york-phvw-vp~18620131[(https://www.houzz.com/photos/traditional-kids-traditional-kids-new-york-phvw-vp~18620131)

Center your sofa under the accent light highlighting the wall. Then a wood carving might be a good option for your wall.

Frames with variety of shapes or a mural for a unique looks.

Is this the norm in your country - why is the coffee table higher than the sofa? Did you remove the legs from the sofa. Are you going to put lamps on that end table, it would help with the height.
