I am not sure I have understood what you are trying to do, apparently displaying different products with very similar designs on the same picture. Like @LMGildersleeve I think it looks too dark and too overloaded.
What I would do is :
- For the tiles, use them only on a subpart of a wall painted with a light solid color, it will highlight them and bring a touch of chic to the bathroom. ( you could do an horizontal frieze for example or just cover a short vertical area behind the bathtub faucet) . The tile joints seem much too wide to me, they should be reduced.
- Towels: I would place them just on a part of the wall painted with light solid color so they could be more visible.
- Curtains: If you place them on a part of the wall painted with light solid color they will also be more visible.
- Wallpaper. Can remain where it is, but only if there’s this painted part I evoked before on the bathroom side.
- Frames: They are quite invisible on this part of the wall, so what you can do is trying to stop the wallpaper at a height just a little bit higher than the sink and put a horizontal wooden stick above to lark the limit properly and on the top part, leave a painted wall to hang your frames and highlight them. I’m going to try to make a small mock-up to show you what I mean.
