Looks similar to my bedroom...

So, you'll be relocating the heating/ac ducting that's between the closets?

Personally don't understand why barn doors are being used so much, especially in this lovely traditional home...

I see nothing rustic in your ideas books so wny rustic flooring in the bedroom. i think you need to strat by deciding your style for thos space as for the closet rip that entire wall out and install Ikea Pax for a fabulous really functional closet.The barn door you picture is like an alien with all the other idea books. Figure out what style you want in the space and BTW if there is no LVP outside that bedroom I would not do that in there.As for wall colors the best place to start with that is your bedding.

Color should be based on the fabrics and textiles in your room.

Agree nothing is rustic; no noisy barn doors. Plus no room.
