The Kitchen is really quite an interesting space with its unusual shape and beautiful cabinets. I would suggest a lighter counter top in a marble or granite but not all white. Possibly a creamy background with some additional colors for accent, like chocolate brown, black or gray. I think you need to replace that tin roof with a drywall ceiling and some recessed lighting, the tin roof is too industrial looking and doesn't tie in well with the cabinets. The walls can be painted a warm beige to compliment the cabinets and keep the space light and cheery. Good Luck!
