I don't like the island sideways, and where you can only get to 3 sides.I'd make these changes:1. bigger doorway - remove the cabinet to the left of the range.2. face the fridge toward the range, rather than 'away from the living area'3. rotate the island and plonk it in the middle of the room, if possible, make it mobile and just have non-specific lighting - 4 recessed lights or something.Rotating the island makes it a work surface for the sink/range area.Have seating 'over hang' on the non-work side, and both ends.
