Gallery Wall

Hi, I’m wondering if someone could help me with this.
I’m doing a small gallery wall in my parents’ bedroom & it looks too symmetrical=i still want it balanced but not mirrored
The point of it is to display family picture, but i still want to mix in art. doesn’t matter the amount of pictures cuz i didn’t order anything. i do want to stick to this canvas painting cuz it goes very well with their bedding…

Any other layout ideas?
