I've been playing with ideas to transfer my impression onto a canvas. This is what I've finished thus far. The colors are slightly off in my photos, but you get the idea.
I painted blue acrylic over gesso textured background, sanded a bit, then added the forest floor and trees.
For this attempt, I sanded after adding all the paint. It's still not what I see in my mind, but I'll keep working on it. It's helping me to play on "paper" before I start a real live canvas.
