Should I have less pictures?

Are you a professional photographer? Is this your studio? You say it is a sitting room and I love the grouping of chairs, the blue and purple colors and the chandelier, but the photos are way beyond overkill if you are not displaying them professionally to attract a clientele. If this is not a commercial enterprise, the shelves should be styled with 1/3 books, 1/3 large decor items, and 1/3 open space. Generally, photos should be limited to groupings of three (a large vertical one behind two smaller ones) layered for interest and effect. For a display as large as yours, I'd have no more than 5-7 spots for such photo groupings, and none of them on adjacent shelves. Mixing of frame styles would also add interest. Most Houzzers find that private areas like the master bedroom, hallway or family room are more appropriate locations for personal photos, and they are more easily admired if sitting on tables, rather than above one's head. Some of the items on your tray (bird, candle, purple glass bottle and silver lotus piece) would be better on the shelves.

I think you may need a variety of objects to balance out the bookshelves. For instance, try taking your 9 favorite photos and grouping them in sets of 3 on random shelves. Add other types of objects (books, candles, bowls, interesting glassware) on the other shelves to add interest. Your seating looks great but the current photo display detracts from it. Experiment with other objects until it feels right, then post more pics. Good luck.

Hang some of those photos around the house. That display of photos has an OCD quality to it. It looks like a display at a frame store.

It would be nice to have a couple of side tables if people will be sitting there having drinks.
