IMO you buy art because you love it not because it “goes “ with the decor. I think one of the giant floral wallpapers would be great on that wall. BTW wood slat blinds and that chandelier do not work together

For me, they remind me of German Romantic painters of the 19th Century, who were influenced by German Romantic authors of the late 18th and early 19th Centuries - my favorite period of German literature. This week I received a copy of "The Fair Haired Eckbert" [Der Blonde Eckbert] by Ludwig Tieck, one of my favorite authors of this period. I do like Novalis (aka Georg Philipp Friedrich Freiherr von Hardenberg) better, but they are very similar. I read all of the German Romantic authors in German when I was getting my degree in German, but recently I have found English translations, which I also find interesting. The Ludwig Tieck book is signed and numbered by the artist who did illustrations for this edition. A few years ago (10 or 12), I found a copy of Die Nachtwachen des Bonaventura, which may also have been written by Ludwig Tieck, since Bonaventura was a pseudonym, and no one know for sure who the real author is. "Novalis" was also a pseudonym, but everyone knew who it was. The copy of Nachtwachen [Night Watches] that I bought was published by the Edinburgh Press much earlier. I always wanted an English translation of this because it was a bit surreal, and I was not sure that what I understood it to mean was correct. It was also illustrated - either wood cuts or lino. Der Blonde Eckbert as lino cut illustrations. Kevin also loves and has been influenced by German Romantic artists.

I think an abstract landscape/water piece, with some color, would look fabulous there … and play into your wonderful views. It would also bring warmth in, while keeping with the very modern style of the room. I’d look on Etsy, on gallery sites, Ebay, and/or visit local places to find a piece that speaks to you. This is a prominent spot — I wouldn’t buy a big piece of generic wall filler. Art here could be the soul of the room. https://magazine.artland.com/top-10-landscape-artists-in-modern-and-contemporary-art/ I do like the idea of three b/w prints you posted — it brings to mind water movement.

The bed frame seems more Beaux Arts to me. Perhaps something like this in place of the travel poster. https://www.greatbigcanvas.com/view/lermitage,1993348/ And a set of small vintage frames on the window wall next to the bed.
