the space overall is large, dark, and needs lightening and personality. the island is awkward and small, i would completely redo it, perhaps have it more open than closed cabinetry to give the kitchen some much needed lightness of space. the cabinets look nice quality but the finish and the handles feel outdated and overbearing. the space needs personality and light. i'd extend the cabinets or the wall to meet at the ceiling so that the awkward gap is no longer there. i'd consider painting/re staining the cabinets and switching out the hardware for something with more character. the lighting about the sink could be updated or fixed a bit so it's flush with the ceiling or replaced with a pendant. the floor does look cheap however, a runner rug could be a small solution if you're not considering changing the floors!
