Greetings! As I mentioned on the previous oak leaf drawing, the cast shadow is too dark. The cast shadow should just be a suggestion to ground the subject to the page, I think you could play up the highlights on the leaves. That does not mean you have to have white areas, but on dark leaves the highlights can be lighter tones of the greens (or whatever the leaf color is). This will give the leaves more dimension.
