Switch the front window and your side entrance door, this way your door is visible from the street. Then turn the window in the pantry into a door to gain access more directly to your kitchen, a closet and maybe a bench for gathering items on the way in or out. It looks like you have to go up a small flight of stairs to get to the door, otherwise I'd say put the additional entrance on the cellar wall on the left of your plan. Depending on space you may need to slide this new mud room entrance to the left and you might have room for a longer closet along the pantry wall and a bench opposite the closet along the outside wall. You would lose the cellar but I am not sure if that is another storage area or access to a basement. Just some ideas. Really like the rest of the layout. Hope my little picture helps to explain my ideas.
