Nice job on your cutting and framing.
When I need a frame I make my own. I use 3/4" x 2". If I paint it I use poplar. I usually rabbit the back about 3/8" x 3/8". I have never used matting or glass. Everyone has to develop their own style and way of doing things. When I first started doing portrait for people I would ask if they wanted it framed for and extra $25. They always chose for me to leave my 1/2" backer painted black sticking out 1/2" all the way around.
