Congratulations! ... for creating a great space to work by making the best of the space you have.
Here's to many happy quilting hours, as you have already put a lot of thought into planning it.
You didn't mention a design wall .... here's a suggestion that might work for you.
Doors are normally blank space ... How about covering those closet doors
with fleece and give yourself a design wall to add to your sewing pleasure!
