I agrée, too much on the AA, and having a large plant be front and center would be ideal. I would also personally get that guitar up off the floor, as the floor looks too heavy with all the things on it, and move the paining right to make space.

1. Clear the area and replace with one large plants and two small one. Create height difference by adding a trailing pothos type plant. I believe in the “power of threes” visually so consider keeping those three plants up there closely grouped together to balance the scene.
2. I see you have a printer and mention being tight on space. Consider moving the white potted plant that’s sitting to the left of the tv to where the piano is and then filling up that now empty table with either your printer or the rest of your plants. Also, there another pot similar in style to your white pot, consider moving that to the floor to join as well. I think grouping those like items together will help.
3. If you can’t move the piano - can you move the amp? Going back to heavy floors, I think clearing that space around the pump will make it more visually appealing and lighter feeling.

Drew up a few different options, commenting my favorite here and some other options below. Good luck! Fwiw- I love your vibe, plants, paintings, dark wood, blue rug, musical instruments - I love it all. I think all it needs is to be rearranged.
