Good feedback, especially about the shadows, and for noticing I had
twice as many faces as I meant to (the extra coplanar faces; it looks
better if you delete the extras).
The reasons I don't like 2d face-camera include:
1. If you've got a bunch of them, they all look identical. With my
rotated faces, paralax makes them all look a little different unless
the camera is really far away.
2. Looking down at 2d trees from above a certain angle, they look
flat. 'course, mine look like green starfish from really high angles,
but I think they look better at, say 60 degrees than 2d trees do.
On the other hand, the 3d version is a lot "denser" looking than it
should be, especially towards the trunk. It has triple or quadruple
the branches and leaves.
Thanks for looking, and for your feedback.
