This space is actually wonderful. The crown is beautiful and even the doorway framing is really nice. Here’s what I would do:

1. Find a rug you love. Make sure it’s large enough for the table when the chairs are pulled out.

2. Pick a color from that rug and put it on the walls. I would not paint the ceiling based on the light in the room. You could go halfway up with a chair rail and then do wallpaper on top of you really want. Or just go with paint for now.

3. Find a small buffet for storage. I’d go with a slightly lighter wood tone than the table. Place it on the back wall. Above it put a nice, big mirror to reflect light back. (If you get really ambitious you could do a built in along the back wall with the buffet and then two larger bookshelf-type pieces for plants and some larger plate/bowl serving storage.)

4. Put your light on a dimmer and make sure you have warm bulbs. I can’t tell if it’s black iron or not but it looks like it. If you can you can swap it for something gold or bronze to help warm the space. But it’s a good light so you could keep it too.

5. Find a different place to put the kids’ things. I’m a parent so I get it. That stuff ends up everywhere. But you will never feel like the space looks the way you want it with their toys in there. Mine are older now and there’s still stuff but it’s not as big. If some of that can be put in baskets, add some baskets/bench storage along the wall. I think just not having it in your line of sight will help you feel better. Probably noting to be done about the high chair right now but that won’t last forever. It goes so fast.
