The first thing I'd check is the quality of the artwork, because a complicated image isn't automatically going to look sophisticated once it's enlarged across an entire wall. I also think the surface finish makes a huge difference, especially when the room gets sunlight from different directions during the day. I ordered peel and stick wall muralssamples and looked at them next to my furniture before committing, which helped me avoid a design that looked impressive online but felt wrong in person.
