Well done, Rina! That looks very nice.

For wall decor , Maybe one of these original artworks would add some texture and contrast to your wall.

We used to have this tapestry hanging above our entryway bench.

Since the front door anchors the wall at one end, putting an entryway mirror there could work, and it would be positioned 90 degrees to the front door thus capturing some natural light. We opted to make our entryway mirror functional as well.

Later on I replaced the tapestry with a large canvas artwork.

So on your wall you could start with an entryway mirror, then a large statement art piece to anchor the middle section, and then differentiate the middle section from the final end using artwork that's perhaps of a different genre or conversely another piece of art by the same artist.

If the other wall is a good view & or a window. A mirror.

This example gives the illusion the room has a window & the room looks bigger & brighter.
