Thanks Rosie. That painting is a pleasure for me on so many levels - the crazy coloring, the "art" labeling, the primitiveness... I am way too constrained to create that freely. And then there is the personal - knowing all DH was going through at the time and his very surprising decision to try painting for respite. It inspires me. For the OP, reflect on what is appealing to you about those museum pieces you like. Crystalize that as best you can. Any gallery would be happy to help you discover works you love, for a price. If that price is prohibitive, try 'lesser' galleries, student art shows, resale shops, art fairs - just look and trust yourself to respond. Let yourself make a mistake or two, it's the only way to learn what you really love. And yes, framing can make all the difference.

If it were hung it would look "squished in" and even if it's left leaning I'm afraid it's still too large. What about putting it in that large empty area to the left and doing some smaller things on the right wall (maybe some black and white family photos? Then you can decide on something else for over the fireplace, which could even be a mirror. If you decide to do that, I would choose something quite a bit smaller and more rectangular than the painting. That wall could really be a beautiful focal point for the room.

Awesome suggestions! I've been sparked! @njmomma: I like this example. As the original buffet comes with a mirror, I don't like it. Perhaps a separate vintage mirror would be nice to reflect some light in the space. Then I can hang pictures around it. @yvonne: I have hordes of pottery and you bring up a good idea; instead of buying more art I should hang my pottery on the wall, after taking off the mirror top. We have quite a few family pictures; in our previous home the buffet was flanked by those vintage items. However as this space has less traffic than the front hallway where I was considering for the family pictures, I'll keep the pottery in this location and the family pictures in the front hallway. @holly: I'm refining my mint favorites. I'm looking at reds, oranges in abstracts and landscapes. However previous suggestions of using pottery may put Minted on the back burner. @tedbixby: yes I have considered putting the wicker chairs on either side of the buffet..To the right of the buffet is a dry sink which is normally in the living room but due to the Christmas tree we had to switch it out with a drop leaf table (which is usually to the right of the buffet under the window). @grover: the room functions as it is. There's a dog pen because we have to pen them when we're gone. We don't use a dining room table, so it doesn't need to function as that. And we have an abundance of antiques but less room than our previous house so we have to find a wall for them. I wish we could put them in storage, but these are my husband's family pieces and he's not interested in doing that. And he's not ready to reduce the inventory, so we have to work with the pieces in the square footage that we have.

I agree that the rug is much too small as well as dark. The tones are taking away from the distinct table base and the coordinating chair legs. As an admitted minimalist, I'd have no rug there or one that's the same color as the floor but textural. The floors are beautiful. Given the many hard reflective surfaces, I think a mirror would be too much and would prefer a textural art piece. The height can't be greater than what's there now due to the vent. Although I really like the candlestick lamps below, it may look cluttered due to the glass cabinet close to the sideboard.
