I need some help with artwork to go on the wall opposite the cabinets with glass fronts (behind where our dining set will be). I attached a picture of my kitchen as well as the roman shade for above the sink, the curtains I will be using on the three sets of sliding doors and the pendant lighting I will be using over the island.

Does anyone have an abstract art suggestion that would go well with my color scheme? I'd like to keep my budget under $200.
