Nik , kitchen looks excellent. I'm curruntly remodeling my kitchen.I'm hand buiding all my own cabinets out of cedar and pine to match my hand built cedar island. I installed about the same type and color tile you did but I set mine on a 45 degree angle with black tile around the island on a 90 degree if can get a visual on that. After seening your before and after pic's. I'm excited to get mine done.
