A narrow wood trim would conceal the gap and I don't think the difference from end to end can be seen.

I would just leave it. I don’t think anyone would notice it.
You will forget about that gap in time.
No ceilings are perfectly straight.
Your accent wall looks great❣️

Throw up a nice crown molding please.

Looks great. Did you paint the wall behind it same as wood? If not, touch up wall in gap with small artist brush and don’t overload the brush with paint. That will help. Then just enjoy it. A prettier light fixture would also be helpful. Or a fandalier if you need air movement.

Looks good!

It’s fine. Once the room has furniture it will never be noticed. Maybe you’ll stop noticing it too! 😊

Put a plant hanger in that corner, once you start getting your furniture in place, and it wont show. I would leave it.

Thanks everyone for your advice and feedback! Decided to just leave it (as most of you have suggested). I’ll be painting the wall this week and furniture will be set up afterwards. I will post an updated photo once it’s all done. Love the fandalier idea. And the planter idea too!

Just don’t hang plant especially over head or bed. Bad Feng Shui. What color are you painting the wall?

Good call! If we were to do the planter, it would be to the left corner near the windows. The wall is going to be Newburg Green from BM. The bed frame is going to be very light grey to help give the contrast.

Left corner near the windows, is where I would put it too.

Gold would look awesome against that ain’t color! Here is quick visual.

Gorgeous!!

It looks beautiful, and I bet you dont even notice that left corner anymore.
