as it is waterproof, non breathable fabric, i'm predicting a damp night inside. unless left totally wide open and even then it will still be moist.
This is my experience owning many tents over the years and having spent some time field testing gear for MSR in the Northwest. massive breathability is crucial in tents and tough to attain in small, WP fabric domes.
but the work is first rate if what we're seeing is a homemade tent project, and one i applaud you for accomplishing, boog.
