My cabinet door prototype

Although I've used routers for nearly 20 years, I have not had the need to make a cabinet door until now, and this is my first attempt at it. This is a protype that I made for my galley cabinet. I have a bag of hinges to use that I picked up at a yard sale years ago, but they all are to inset the door 3/8" inside the frame, and I didn't inset the middle shelf frame, so I have to make 4 smaller doors rather than 2 large ones. I put an oak ply panel in the prototype, but thought about buying a sheet of 14" birch so that the color is all nearly the same. But, the contrast with the oak isn't bad either and my wife likes it, so i'll probably use the oak that I have.
The door frame pieces are butt-joined with pocket hole screws, as my mitering attempt wasn't so hot. It is hard to see it, but the outside face edge has a 5/16" roundover. The in side face edge was done with a 5/16" cove molding bit after the door frame was constructed. The inside outer edges are dadoed 3/8" by 3/8" to fit inside the door frame, and the panel is inset 3/8" from the face of the door.
