Keep trim white and accent wall a wheat color you want. To bring in colors to bring them together

I love the pic on the left and by the way what color green?

Change your curtains to go down to the floor... They will look better

Green makes for a very restful bedroom. While I see why you've chosen the inspiration room, I might consider something a bit different. Put the tall chest between the windows with art above, two panels at each window to the floor. Put your bed where the dresser is so you'll have plenty of room for the picture gallery to extend to 75% of the headboard width. Hopefully, another wall is wide enough for the dresser, but we are only seeing two walls in your pics.

Personally, I'm not a fan of accent walls. What we've done instead in a few rooms is to put a piece of molding higher up on the wall and then paint white above or below it. That way, you get the color but it's not so dark. Good luck with whatever you decide! :)

I am not a fan of accent walls per se. If there is a focal point it can be worth doing it. For example your inspiration room doesn't need an accent wall.If you really feel there is bland and want to do something, instead use a one panel of wallpaper straight up or offset to create an interesting point (dresser in front etc) which can be fun.

Why anyone would put a bed in front of windows when there are suitable walls available, I will never understand. So I do agree with decoenthusiaste.
