I am also working on a more ambitious landscape in the mornings of slanted shadows on a tree-lined path. It's taking me several sessions to capture it all but I'll post it soon.
Workshops and teachers are valuable, but really nothing beats painting and drawing every single day. I have learned so much in the last couple weeks of painting every day. I dream every night about brush strokes and the feel of a brush dragging paint. There really is nothing like paint.
