From a comfort standpoint here in climate zone 4 we think this will be a good tradeoff to using 2 6 walls that have a moderately higher r value but a bit more thermal bridging. The asphalt felt paper should go over the sheathing wrap which should also wrap the corners at least 6 in. Consider a wood shed floor treated lumber joists and plywood.
