@Natalie Medved I love seeing well-booked and high-priced competition with bad decor, it's a good sign that with some thought you can clean up!
I would replace the ceiling fan. It's not terrible, but a newer black ceiling fan will make the photos pop. Similar to the way a new roof helps an exterior.
If you look at professional product photos for homewares, there is usually a single (or at most a small handful of) non-neutral color(s) that is repeated throughout various elements in the room (area rug, throw pillow, bed scarf, vase/sculpture, picture etc). Not only do the colors make the photo pop, the pattern has a naturally calming effect on the mind and implies that your place is orderly in addition to being stylish! Fake plants are great too and add freshness, nobody cares that they are fake.
Make sure your decor fits the theme of your area, or at the very least don't have anything that is in conflict. Don't have a photo of the Maldives if you are in the Northeast. Finding vintage items that relate to your area and old photographs can add a lot of character as well.
