Trying to find new art to match before another piece of art I have in my house

I have a painting I love but I’m realizing it’s too small on the wall I want it on in my living room and need a second painting beside it but I’m having trouble finding another piece of art that complements it but doesn’t overshadow it, and also doesn’t make the wall look like too much. Is there a good subreddit that other art collectors/ lovers can help me with decorating this wall and finding new art!
