Instead of hanging artwork or a shelf, have you considered a textured wallpaper like a natural grasscloth. It has a softer three dimensional feel and may add a lot to a room where all the walls are painted. Also I would change out the sconces for swing arm lamps. This way you can remove the table lamps giving you more space on your side tables. Also lower the swing arms so that they are more useful as reading lights. If you need more general lighting possibly add some LED high hats on dimmers. Looking forward to progress shots!

HI -- I think you should get rid of the sconces --- they do not fit the look of the space . Visit around to some galleries and poster shops or any other Art outlets to see what you like , then find something that is what you like the most.

Right now, the couch and the walls appear to be the same color. I would choose a different color for the wall behind the couch and then choose a painting that pulls the couch color and accent colors together.

Did you try that tree artwork that is in your dining room, behind the sofa? It might look nice. If it is not wide enough, then maybe add a sofa table and merchandise it - this is shown in the comments made by patriciarhall.

Try the dining room tree art over the sofa, remove all the little stuff on walls in living room and make a collage of them in the dining room....this way you can repurpose and be economical at the same time. That being said, I would pick the brightest color out of the tree art and another bright color out of your easy chair and do solid intensly saturated with color pillows. If you want a more modern look, you could hang your curtains from the ceiling after adding one of your pillow colors in fabric bands to the curtains so they touch the floor. This will add a bit more color to the room and therefor more interest and detail.

1. Light blue dark blue but match to rest of colors in room

4. Gallery wall in dining room. It is fine to mix pictures and object together, start with biggest item in middle and go from there.....about three inches to 6 inches apart.....lay out on floor and see what you think?

I also think you could use taller lamps in an accent color too. These are 32 inches tall and could work with your love of blue......or any accent color that shows in the chair or the rug! Good luck.
