If there is a wall against which you can set the back of your dresser, preferably with the window/light to the left if you are right handed, then do that.

You like pink? You're wanting to keep the wall and curtain colors you have? (guessing, yes).

You don't show a chest of drawers. You might consider a pair of narrow cabinets with storage for use as bedside tables -- with tall thin lamps -- the height you'd need for reading in bed -- and white shades (medium/small size for a small room).

The bedding you choose will determine the look of this room.

Find a comforter/bedspread you like in a full (or queen size if you want to lose the dust ruffle) and a pair of matching pillow shams. Then pause to consider what else your room needs before doing more. If pink is to be your core decorating color, then stay with pastel colors. Lighter colors can help a small room not look even smaller. The colors of the sheets and pillow cases and blankets beneath them could be white or any pastel neutral color of your choosing (including pink).

After you find your comforter/bedspread and shams, post another pic.

Have fun with your search.

Something like these as bedside units could double as underwear storage:
