Center the middle row with the chandelier. Then I would cut the spacing to 2" between each photo.

IMO family pics are best hung in more private spaces like hallways to bedrooms for instance , Those are hung to far apart and honestly a nice piece of art quite large would be a better choice. I know newly weds want to show off their love so do them in a hallway or a nice photo album on the coffee table.

I would either add more or do one larger one.

Center with chandelier and then add a plant in the corner.

If you plan to keep them, move them closer together so they appear as a unit. They’re too far apart now.

One way or another, they should be closer together. I would be tempted to centre to table and add a tall plant to balance. If unsure, tape up exact sized paper so you can get a sense of how it feels.

Thanks everyone! Ended up scooting them closer together and centering with the table!
