3 things I aim for when building a blind- keep my scent in, keep the bugs out, and have plenty of windows . There is one window that opens on each side, the rest are fixed viewing windows made from tinted plexi glass. I bought the opening windows from deer view windows. The view from the inside is great and from the outside the windows look mostly black , especially when the suns out.
Everything is wrapped, caulked, and taped in redundancy to make sure the blind is air tight. The reflectex wrap makes it very quiet inside.
The blind has too much movement when you move around inside so it will be ratchet strapped 4 ways to earth anchors in the ground.
I built it almost completely out of material I had laying around so that's why some of the colors don't match very well .lol
