Okay, here's what use I've put my pile of leaves to so far. This isn't
the final version by any means, but it gives some idea of what it'll end
up looking like. For anyone curious, the sidewalk texture is procedural.

I really like the trunk and the sidewalk... but the leaves doesn't look as
leaves for me, at least at this disatance (well, not many oaks here to
compare).

I've had a number of people say that. I kinda see what they mean, but
since the leaves are pretty accurately shaped, I don't really know
what's wrong or how to fix it. I suppose if worst comes to worst, I can
wait until the leaves ACTUALLY fall off the oaks here and see what it
looks like.

One of the problems can be that some of the leaves seem to float a bit
over the terrain, casting confusing shadows. The other is perhaps that the
leaves thickness seems excessive, I would expect more flat leaves. You
know, sometimes the archetype is more convincing than the real thing... :)

Looks promising, but the leaves should IMO lie flatter on the ground. The
tree is very straight, making it a bit irregular and broader at the base
would be a good idea probably.

I love the sidewalk and the ground. Great textures. What bothers me
about the leaves is the coloring. I wouldn't expect to find purplish and
grey leaves - at least not so many. You could try a more
green-yellow-orange-brown color scheme, and see how that works.

Being one-sided meshes, the leaves are quite thin. ;) They have a little
bit of warping and curling, but not enough to give them much volume.
As far as the floating.. I'm aware of the problem, but I don't know how
to fix it; the leaves are placed on the terrain with trace() and
shouldn't be sitting at varying heights as they are now.

Nice start on the project. I live in a woods with lots of oaks, maples, and
beeches. The oak tree base should spread out at the bottom, should be
irregular in shape, and should show the trunk branching into roots.
The leaves are to small, not irregular enough in shape, and oddly colored.
They should be larger, more differentiated in shape and size, brown to red
with more yellows and no green.
FWIW.

The current trunk is just a stand-in; it will be replaced with a more
realistic trunk later.

The leaves are actually made more or less to scale, based on some real
oak leaves that I went out and looked at, and AFAIK, there's no way to
change their shape (except with uneven scaling) that wouldn't consume
massive amounts of memory. However, I will certainly look into fixing
the colors.

The leaves being one sided meshes, it shouldn't be too hard to add a degree
of randomness to their exterior outline (use the random number generator).
The lobes in the leaves should be of varying sizes as well.
As to the size of the leaves, given the scale defined by the sidewalk
segments, the leaves are too small. Indeed, if we assume the sidewalk is 3
feet wide, the leaves are 0.95 inches long. The leaves on my oak trees are
at least 4 to 6 inches long. So, we can see that the leaf sizing in your
image is off by a factor of 5 (or so)
You could keep some as small as they currently are, but the others should be
larger. In addition, the larger leaves should be slightly curled at the
edge but flatter in the middle.
