The island is in the direct path between the sink and refrigerator. If you placed the refrigerator closer to the mudroom door with just a narrow cabinet to it's left, and replaced the pantry closet with cabinetry in the fridge location, at least it would be a more direct route.

It may be a kitchen to consider an upside down U plan rather than an island.

I agree that an upside-down U would work much better here. In other words, turn the peninsula 90 degrees and attach it to the end of the counter where the dishwasher is shown. (If the measurements are such that the dishwasher then wouldn't fit there, you can either make the sink/DW leg a bit longer so it will fit or put the DW in the new leg [the former peninsula]). This will also give you smoother traffic patterns since the people seated at the counter overhang will be in the eating area instead of in the kitchen. With your floorplan, having them in the kitchen will block the path to the mudroom and laundry room. It will get annoying pretty quick, probably.

Any reason your plan shows a 50/50 double-bowl sink? If you have a dishwasher, 30/70 double bowls or single bowls are usually much more practical. Equal sized double bowls really only come in handy if you do a lot of handwashing, and even then they can be annoying because neither bowl is big enough to soak a frying pan or cookie sheet.
