Love your room. I have one devoted to sewing also, with a little, little corner computer desk where I pay bills, etc. It is definitely not in order yet!
I like your planning and development area; ie: the couch and bookcases with magazines.
Questions: Is that a window above your long desk or just a lighting source that has bolts of fabric in it?
And are you going to be reusing that countertop? It looks so slick and smooth, great thing in a quilting area.
I am so jealous of your getting a longarm...I am just getting started learning to quilt on my sewing machine....maybe in a year or two...
