very lovely. I got the same feeling of the tree being non-vertical, but to be honest, I can live with a forest where trees are not vertical. I'm surprised that the top of the tree's canopy is so smooth, almost like an old-fashioned haystack :-/
those little patterns for flowers and grass are just marvelous!
How do you build such tree canopy, btw ? Do you have like a leaf-brush that you plot in due places, or do you rather go "it's not that hard to draw them all" ?
