I like the placement of your microwave-- good to have it off the counter! And I really like the dark cabinets contrasted with the light counters and backsplash.
How about a pretty valance over the kitchen window? You could use a little color there and a simple box pleat valance would look nice there. You could select a patterned fabric (I recommend a stripe or geometric) that has some of the dark brown from the cabinets, some of the cream from the floor and counters, and a third color pulled from something in your adjacent family room-- maybe green?
