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.

I can't seem to find huge oversized wall art in the Los Angeles area. Every store I go to has large art, but I'm looking for art that will fill up huge tall 20-30 foot ceilings. Anyone know what stores i can go to in the LA or Orange County areas?

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.

You can contact the company that sells the bed. Maybe they can direct you further. https://www.fortywinks.com.au/products/bedroom-furniture/abeille-qb-bed
