What's your family composition? Do you need to accommodate a significant other and/or children? That makes a difference in what will/will not work well.

It looks like the measurements for aisles are incorrectly measured cabinet-to-cabinet and cabinet run depths/widths are incorrectly measured without considering counter overhangs in the front. Aisles should be measured to/from the items sticking out into the aisle the farthest - counter edges, appliance handles, etc. Cabinet run widths/depths should include counter overhangs on all sides. The 24" measurement for cabinets/cabinet runs only includes the cabinet boxes -- it does not include cabinet doors/drawer fronts or counter overhangs (1.5" beyond cabinet boxes).

You also have 5" less than the recommended minimum of 15" of overhang for seating. Skimping will not "save space" when someone is seated there -- people will take up the same amount of room, they'll just be uncomfortable b/c they will have to lean far forward to reach the counter.

Where's your table? If directly across from the peninsula, do you have enough room for seats at both locations? You should have around 60" b/w a counter with seating and a table with seating. Do you really need seats at the counter?

How much filler is there b/w the DW and the corner? How deep is your range, including any necessary space behind it? I question whether it will really clear the range's oven door. (What's the make and model # of your range?)
