Not enough information.

Without knowing your location or your site plan I would either put the sink in the island or keep it under the window and put a few trellises along the pole barn so you have something nice to look at.

Are there no views from where you placed the pantry and closet?

Not enough information, but based on what you gave us, move the pantry and closet away from the outside corner and place the kitchen there.

Where are the views, if any?

You may want to check with the local zoning department, some do not allow one building to be less than ten feet from any other building.

Which side is South, views, neighbors?

As drawn, in the island. But it's always a bad idea to put a storage space (pantry) in the corner of a house.
