I ahve to say personal pics are never my favorite in non private spaces. I also think if you have one piece you love use it by itself. I find gallery walls generally take away from each piece that is displayed I like my art to be stand alone and be appreciated by it self I will tell you if you want help witht his you need to post pics of all the pieces you are thinking of using. There are people on here who love gallery walls and are quite helpful

It may look odd to insert a sentimental piece on a wall gallery ...with otherwise decorative art...and in a dining room it may be a distraction ...personal pictures are nice when placed where people can linger comfortably ...for viewing

I think art should always be personal in some sense (and not merely chosen to fill a blank space), and should be hung in your home wherever it would please you to see it. There are no "rules". I absolutely think you can mix your canvas with other framed pieces, and even pieces of varying mediums. My powder room gallery walls are hung with unframed canvases, framed originals and prints, framed photos, and textiles. It works because it's visually interesting ... and because it speaks to who we are and what the lives in our household enjoy.

I have vintage Native American photographic portraits hanging in my dining room. Like I said, no "rules". 😁

I like personal touches in a person's personal home so I am a dissenter.

What I have done is outlined in the following.

Take all of your pictures and lay them out on the floor on the floor. Place them in a configuration that makes shape and colour sense and also makes a fairly nice shape if you wish it to be formal.

Once you have something pleasing to your eye check your measurements and measure it on the wall. Make sure you have every picture placed exactly the way you want it. Then proceed to hang the pictures and and the artwork.

Some people use blue painters tape and design the shape on the wall. That works if you have all your colours and shapes measured and you know they're going to look good together.
