They look fine to me. I like the rug too but it’s not wide enough.

Generally the chair style seems to go with the table, but hard to be 100% sure, because AI photos usually make color/lighting look "perfect" when that isn't how things look in person.

When you get another rug it should be laid the other way and be at least 24"+ wider than the table to move the chairs in and out

Change the configuration of the table so the chairs are diagonally placed.

If you don't already own the arched cabinet select one that is taller. This one seems too short for the space.
