BM quiet moments is my favorite blue-green light paint, it's just sooo yummy. Check the page below for photos of rooms done in above color paint.[Quiet Moments rooms[(https://www.houzz.com/photos/benjamin-moore-quiet-moments-phbr0lbl-bl~l_425)

In Addition to Quiet Moments, look at BM Woodlawn Blue, Yarmouth Blue, Wedgewood Gray. Wythe Blue, Palladian Blue.

However, I'd put bedding first unless you're planning on going with white --- which you can always bleach if it's cotton.

What will you be doing beneath the window?

If the oak trim stays, the green on the wall will make the oak look even redder. Here is the quiet moments.

Consider refinishing the bedroom set. You'll never get to your inspiration picture with all that pine.

We decided to eliminate the soffit and go with wall sconces on either side. Original idea was to recess lighting behind the soffit. Probably will put a comfy chair or two under the window. It has a great view and is a nice place to sit and/or read.

I love the Quiet Moments in Yayagal's third picture with the pine chest. Have you considered painting the door and trim white? That would help with paint selection and your pine furniture would still look good with soft, light accessories.

huh?

I think at this point we are going to keep the natural wood trim and the pine bedroom set. Is there a color palette that would work better and still create that serene feel? I am wondering if a stronger color might balance the woodwork better than the pale blues and greens.

Took your inspiration photo wall color and superimposed it on your bedroom photo so you can see the difference in color. Then used the SW app to determine the green paint color. Maybe this will help you select some paint chips that you can have matched with the paint of your choice.
