Anatomy of a painting - Gifford Covered Bridge in Winter

I like to keep a record of how my paintings progress and occasionally share the. This is the photographic record of how my Gifford Covered Bridge In Winter progressed. It started with a photo from Vermont-Four-Seasons-Photography page on Facebook and went from there.
As you can see, my style is to block out things in black, let it dry and the paint over that, painting the entire background. The anything in front of that, I block out in black and paint over that. I'm trying for depth.
