For me, your bedroom is missing two things - style cohesion and texture. For starters, I would replace the white pillow with two of these: [houzz=] Your bedside lamps are nice, but now with the gray comforter they need a new style: [houzz=] There's an outlet right where a headboard would go, so instead, I like this art over your bed: [houzz=] or if you prefer some color and something quirky: [houzz=] For curtains, see if you like any of these: [houzz=] or [houzz=] or [houzz=] For nightstands, try these: [houzz=] If you decide to paint your wall charcoal gray, be sure to add art with color behind the bed.

Start with looking through photos and saving them the ones you like by adding to your ideabooks.

Buy the bedding you love and then go from there to doing the rest of the space, paint is cheap so leave it till the end of the process and match to something in the bedding would be my suggestion.
