If you as pictures it will be easier to get help.

I’d bring that sun thingie down at least a foot or so. Unless there’s going to be a mantel. If there’s going to be a mantel, I’d take the sun thingie away.

You didn’t give us a very good picture of the bookshelves. Back up and let us see the whole wall.

agree with @littlebug Zone 5 Missouri ^ move the sun burst to another spot in the home, a mudroom, garden room, porch.

More ideas for placement on shelves. Have some open spaces.

Here is a better picture of the fireplace and bookshelves

Before putting anything on the shelves I would finish them a bit more. There is a funny gap and the bottom right shelf is weirdly large. Then I would look at inspiration pictures for ideas.

^Agree with WestCoast…check inspo pix online. Simple is more appealing with shelves for me than loading them up.

Thanks for the new pix. I can see the whole bookcase now in your fairly narrow room.

Hopefully someone will be coming to fully finish the bookcase - as said above there’s some wonkiness going on.

At first glance, without enlarging the picture, I thought there were a couple of baskets on the shelves (I see now they are cardboard boxes). But the color of those boxes, I thought, was quite attractive. So maybe you could consider getting some baskets that color for storing small items on a few shelves.

I like your sun, but its coloring is so similar to the stone on your chimney breast that it isn’t seen to advantage. I hope you can find a happier place to display it.

I’m a fan of having books on bookshelves, but perhaps you already have your books beautifully shelved elsewhere in your home. If you do, then once your shelves are straightened out, don’t rush to fill them. Find things you treasure, and take time to balance your display. Start with things you already own first. Objects that don’t have meaning for you aren’t worth giving houseroom, in my opinion. It’s okay to let shelves sit empty till they tell you what they want.
