I think I'd put a chrome towel shelf over the tub area. Maybe one with a bar on the bottom would come in handy to hang hand washables. The area to the left of the sink isn't that large so I'd have to think about that. Do you need a place to hang a washcloth or hand towels? If so, I'd get a metal towel bar that matches your sconces. I'd probably put any pictures on the long wall and get brushed metal frames to match the sconces. You already have enough blue in the room, so I'd go with the black-eyed susans or hibiscus to bring in another color. Since one is a cool color and the other warm, I'm not sure if I'd do both of those together. What else do you have in your garden? I know there are ways to doctor photos so they look like paintings, but I never heard of this one. How handy are you? Here is a link that might be useful: digital photo + water

As a home stager and amazon affiliate, I still love the look of floating shelves: https://amzn.to/35yl8GU I also like the look of metal wall art and I'm not sure what your taste is. At Home and Amazon both have great metal wall art options. A wall clock never goes out of style: https://amzn.to/33k87OE I've never lost my love of floating shelves because you can dress them up with your favorite decor items and when spaced out well, it never has an overwhelming look. #affiliate link

I'm looking for a simple circle - not heavy wood or mirror or much color.... or you might like some texture like chairs and console... ?

Hang the rod at least 3" higher and 3" wider than door frame. The drapes are going to call attention to the doors and to the outside. So do some exterior decoration out there.
