Both of those pieces are too small for that size wall. I think you need to upgrade one of those pieces so they're larger before thinking about art.

I think that wall begs for one large statement piece.

I would add a larger, more colourful rug, in addition to the above suggestions.

I agree you need a more substantial console and maybe a chair there. Or a long bench. After that the art is up to you. I think entryway art should say something about the family that lives there: What would you like people to know about your background, activities, interests, travels, hobbies, etc? Find art that gives people a clue about who you are and what you like.

You mentioned your loved the stool and table, which is too bad for this location, because your foyer could be so much nicer, more useful and impactful. Had to be honest. See pictures below as a comparison. Before adding anything to the walls, be sure you are keeping things the way they are.

Like everyone else stated, what you have is too small for the space. What you need is something bigger so that it fits the space. Here are some of our designs just to let you see the type of things that might work, size wise that is. Note the bench and the table.
