Much better - good shadows that immediately adds depth and three-dimensional understanding.
Do be careful where your shadows on the wall cross another leaf. They should not cross directly over them - unless the leaf is plastered flat to the wall. If the midground leaf is half way between the foreground shadow-casting leaf and the wood, the shadow will fall lower across that leaf - that is nearer to the foreground leaf.
See below for quick demo.
And I'll post some more assistance to the classroom for everyone.
