Cool shot. I like people for scale and interest. Clearly not the subject, but a welcome addition to many landscapes or architectural shots IMHO. Not crazy about the "looking through a peephole" borders. I spent just about as much time exploring the borders as I did exploring the content. Creating a margin of negative ( black ) space around the entire image will better define the margins of the photo and create less attraction to finding the edges. i.e. expand canvas black 2 inches. This will be exacerbated when framing for a wall.
Nicely done stitch... at this res... Hope it looks great at higher DPI!
