Looking good! They do go up fast, but only if you've done it a few hundred times. I'd hate to figure out how to do this on my own. I did a tiny 6 x 8 shed and it about wooped me (was working on my own).
This heat is miserable.
They look OK when the area is clear, small when the poles go in. OK once the frame is done, and then small again after you've had it for a while and it fills with stuff. You can't really win, but the only way to loose is not have the building.
