I like the pull out shelves

try to define what you will place in the closet/pantry, e.g. cleaning materials, brooms, mops,pails, or just food items?
consider a roll out cart ? measure the right wall -for perhaps wall rack about 6" deep for canned goods? perhaps a door mounted rack of shelves for smaller items?
consider adding a light below the shelf and 12-18" deep adjustable shelves at the rear

It would just be food items for the most part and probably just a small swiffer mop. I do like the idea of the slide out shelves. Thanks for all the suggestions!
