Best window design for bow blind?

[afishinman14]

Anyone got any ideas or suggestions on a window design for a bow blind? I've got a bunch of ideas in my head, with rectangles, triangles, and diamonds. Gonna try to build a bow blind. Like to explore all my options. Trying to maximize concealment, while also presenting a practical space to see and shoot through from all angles. Pics are always welcome!

I like straight up and down.
This was just a rifle window until I converted it.
