That island is bananas. And not in a good way. I would not have seating at the island for more than 3-4 people and increase the size of the dining room.

Move the fridge to the short wall on the hall side, add the microwave over there and have a snack area. The range hood will become a singular focal point on the back wall.

I agree with making the Island smaller. It will look odd for the island to extend longer into the room than your kitchen counter. I also like the frig moved to the hallway wall. Someone getting in the frig will not be in the way of a person at the sink and it gives you more working area on each side of the stove. Also in the old spot the frig boxed off the end of the counter. Having the end of the counter open to the room will make it seem larger and more open.

You might also want to rethink your pantry door opening in instead of out. My pantry is the same size and the door currently opens in and I am changing it to open out. The door opening in makes it much smaller and limits hanging things on the wall. I am adding a "slat wall" system like the one pictured below to my pantry. You can see in this photo though how the door opening in will block quite a bit of hanging area.

And the post should scoot down to align with the pantry wall. It'll define a larger dining room and frame your kitchen better.
