HELP!

Jenny left a comment on a post from about 2 weeks ago asking about my house situation and I didn't want to answer her because I didn't want to jinx anything. The process is right on schedule and I'm in the process of buying this house here.
It's 4 bed, 2.5 bath and 1600 square feet. It looks like a 1 car but it's really a two that you park bumper to bumper. The appraisal came in lower than what I offered so I'm waiting to hear if they'll accept the appraised price and should hear something today.
I've already picked out colors for the living room-any and every shade of brown with touches of green and blue. The big debate I have is my bedroom. I want the walls a light gray, the bedding is white and most likely the furniture will be black.

I picked my accent color as gold-ish yellow-

I bought the above plate at Pier 1-inspired idea from this photo:

I pulled some things from my room and put all the colors together and took a picture to see what it could look like. My picture is more accurate of the color than the pier 1 picture.

Will those colors look stupid? Obviously the golden yellow won't be a main color, just accents of it around the room. I did think an aqua blue would be an easier color to coordinate.
Your thoughts? I don't want to spend a ton of money but I'm ok with spending for furniture that I plan on keeping for awhile. I need someone with a cuter style to tell me what to do and I'll just agree to it.
