I just have to tell myself that all good things come in time:) Yes!! Especially when it comes to finding art. There are loads of places to look though. Seeking art in person is a lot of fun but online can be a heck of a lot easier and you have practically the whole world at your disposal. If it can help any, Artfinder just sent me a curated list of art below $650: Artfinder - paintings below $650) Other sources: ebay, etsy, 20x200, Saatchiart, 1stdibs, ebth, Tappan Collective, Daily painters (small pieces)... Enjoy the process!

Gaea, your original question was about hanging artwork on a wall with an off-center couch. The seating arrangement needs to be addressed before hanging art. The sofas should be closer together so they feel more connected, and you need a coffee table large enough for both of them to reach. You can move the back sofa left, move the window sofa forward, then determine what size your coffee table needs to be. I would lose the white round coffee table--it's out of scale--and choose something large and square to serve both sofas. Once you have the sofas positioned, you can hang art centered over the sofa on the back wall. A separate piece can go behind the piano. Here are your selections of lamps and art:

I decided to keep painted "stick art" where it is, in the DR. Most houzzies say they liked it best where it is. As I create more pieces of art I might shuffle the art around on the various large walls. My next conquest, after a few mundane items, may be a wall plaque sort of deal in the Brutalism style. I lifted this idea from a Restoration Hardware lamp and think I might make wall art with a similar pattern..

Hi cormar, LOL, see that's why I'm not a pro, can't visualize what looks good, only know when I see something that imo does not. I like the idea of putting the TV on the wall, with a credenza, as ilikefriday has done. With those two windows hopefully the pros will come in with some various ideas. I would like to see something that keeps the windows, and incorporates them into the design, something fairly simple. Oh here's a thought, what if you centre the TV under the windows, and put just one piece of vertical art on the other side.
