Your space is beautiful! I love the organized look. I find I can only really relax at sewing if there is nothing I need to tidy up. I get distracted by the mess.
You have a beautiful big window. My sewing room is in the basement, and though it's a bright room, the window is small and I would love to have more natural light.
When my daughter leaves home (she's only nine, and I am thinking way too far ahead here) I will convert her upstairs bedroom into my sewing room. Lots of light and space for all of my stuff. Then I will even have room for a quilting frame and machine! I'd better start saving - I have only about nine years to save up!
