I find the gold frames are at odds with you rustic table and bench. I’d prefer to see more interest in that corner with some colourful window treatments. No art, no mirror.

Agreed ^ - the table is casual with a bench, I’d do brighter, more fun and casual art if it were me

Unfortunately, the watercolors don't show up there. I think you need something colorful with blue to tie in with the bench fabric. We can't see the other side of window-maybe something on each side of window. Mirror doesn't work there.

The watercolors are probably nice but you can't see them in this environment. Find a new place for them. Your wall decor should be a bit more bold based on your furnishings selection.

You have bench seating, so you don’t want art to be placed where a head might crash into it. Textiles, on the other hand, are at least soft and more forgiving. Have you considered a back cushion? I know your wall is flat, not angled for leaning back, but a back cushion would give you some visual interest and you can place artwork or textile hangings above it. A clock might be nice too.

Cannot see the entire wall on the left of the window but here are some ideas for style. Place accent pillows on the benches, a canvas on the wall, and hang natural wicker baskets or paint them in a colour to coordinate with your decor.

If the watercolors are personal to you and you want to use them, consider having them color matted and reframed so they're larger. The glass on them should be less glare also.

We think, since people will be sitting there, the artwork might not work well if someone is to lean back. Are you going to be putting in back cushions? Please note in the image below and where we placed the artwork in the breakfast nook area:
