Door construction

Finished building my doors yesterday. Started out thinking I would do the somewhat standard 1 by lumber frame with insulation sandwiched between 1/4" plywood skins. But as I was building the frame out of oak, it came to me to put the frame on the exterior since I'm building a woody. There are 2 layers of 1/4" oak plywood behind the frame, one facing out and the other facing inward. No insulation in the door, but I like the look. Doors are about 1 1/4" thick. Windows from Grant. Latch and deadbolt from Lowe's.
