  It looks great, of course, but I still think that a proper bump map would
achieve an almost identical result (unless you zoom very near the leaf) and
the rendering time would be quite smaller.
  Of course there have to be a way of representing the leaf itself. Perhaps
a mesh (number of triangles would be a lot smaller than with the heightfield).
The advantage of the mesh would be that you could bend the leaf, which I think
is not possible with the heighfield.
