Ideas on how i should design my new room?

I'd do a feature wall with your favorite color, then a neutral color on all of the other walls.

Once your room is painted, move your furniture around so that you have the best placements with the most amount of space.

Add a big zebra striped area rug on your floor like this Zebra area rug. Not only will it liven up your floor, but it will establish a zebra theme to your room. Once you have something large like an area rug, you can add smaller zebra elements such as picture frames, throw pillows, blankets, and candles.
