IMO the whole thing is a bit of a mess, I am sure they all mean something to you but to my eye there is nothing connecting them just a bunch of stuff hung on a wall. Maybe explain what you are trying to do but usually one larger piece of art is easier to handle.You do not even say what room this is.

They look like they are just randomly hung with no relation to each other. You need to look up gallery wall ideas, group them closer together and laid out intentionally as a group. Looks like there are photos on the dresser, maybe add those to the wall grouping and then try to keep the dresser free of stuff if there is a large grouping over top. Good luck!

it's the bedroom and Moroccan theamed
