Here's some suggestion for your wall you might like......to know more about my Art work and collections please visit my shop -

****CUSTOM SIZE AVAILABLE ****

It looks like you want something relatively brighter. The room looks pretty dark. If you want brighter try something like this.

otherwise if you mostly want to match the style table you have go with something like this

Good luck and Have fun :-)

I'd do art instead of a mirror. Mirrors generally just reflect the other wall, or yourself while eating.

Your chair appear to match the table design. What is it you don't like? Do you want padded, or just a different design?

A series of 2-3 pendants would also look nice.
