Nice. Like walking a trail at night with a flashlight. Looks nice.
Suggestion would be to perhaps start thinking in terms of not merely going around the canvas filling space with leaf leaf leaf, but to start thinking in terms of grouping clusters which create shapes that you can then use as design elements more so than pattern. Some artists use pattern all the time. But my suggestion is to add variety. Makes it more interesting in my opinion.
