You can also create cast shadows by adding a light above the horizon lines and mapping the lines where they intersect, maybe practice that and get a good handle on it and then move on to winging your own light projection lines from points out of frame.

The perspective boxes where you used guidelines look good, keep using guidelines until you feel comfortable without them. Also try to use darker gradients with your shadows.
