Is that a window in center above the hearth? Is rock just a facade? Looks like you have a mixture of furniture styles. Windows look more of the modern style while drapes are traditional. I would say pick one style and go with that. From the windows I'd be leaning modern/ contemporary. If the rock is just stuck on wall take it off. Replace with horizontal wood planks stained same as your door casings. No mantle. If that is a window I would either have a stained glass insert made (again using modern lines) or do a faux stain glass painting treatment to add some visual interest.

Just some ideas to think about? Uber big arc light Round uber big leather ottoman Long floor to ceiling curtains with print or color 4 inch trim on either side of the panels hung between the windows. Art work set in the cubes similar but different, as in perhaps, musical instruments, African masks, Art Deco Lallique vases, anything that reflects You translated into art. Back cubes with mirrors and put puck light in the top of each for nighttime drama and to light the art work. A large Fiddle Fig tree as the trendy green this year. Possibly smoked mirror above the TV screen as big as the cut out. Bring it on.

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.

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.
