Hi Geoff,
Yes. I'm using MegaPov, but I'm not using
any radiosity. I tried it, but it was just way too
slow to render. I might try it again.
I'll try moving the light source around. Do you
think you should be able to see the trunk of the
tree in the shadows? I wasn't sure. I think you
are right about it's position being the reason
for the flatness of the leaves. There's actually
quite a bit of phong for the leaves, but it just
won't show up. I'll try moving the camera
around just to take a look from overhead to
get a better idea of what's going on.
I'd love to see a detail shot of your rust, please
post.
Again, I really appreciate everyone's comments,
suggestions and help!

Thanks D.J.,
Thank you for the compliments. Margus
mentioned the same kind of feeling about
it. It feels wonderful to have made something
that connects with others. Maybe we've all
been there?
Best regards...

No, not too strong, but too regular. Maybe try granite or turbulent
crackle (slow!) instead.

Yes, probably, unless you want muddy water :-)
Maybe have a look at the water finish tutorial on my site.

Thanks Khaver,
I'll try that tonight. Going to be working
on getting the leaves looking good next.
There's only a simple normal on them now,
so I'll try something more sophisticated.
Thanks for your help!

Try a normal_map, start with ridiculously high values then reduce them! or
normal_maps within normal_maps
Here's an example
normal{
average normal_map{
[0 ripples 500 scale <2, 55,10>/5 warp{turbulence .25}rotate y*-20
translate x*.5]
[.5 ripples normal_map{[0 agate 5 scale <2, 5,10>/5][.5 wrinkles 5
scale<2, 5,10>/8]} rotate y*76]
}
scale.5
}
BTW the pic is much improved.

I may be giving up radiosity myself at this point. It's taking *really*
long.

Depends on what you mean. The trunk should cast a shadow, certainly. If
the part is already in a shadow, then the trunk shouldn't make it noticably
darker (well, in reality it would, slightly), but if it's itself the first
shadow object, it should be nice and dark.

Some nice shadows, maybe even longish ones to the right (left? No, right,
I'd think) might be nice. Like you're seeing this place at/near sunset. Sunset
is a twilight time, a time of change to something darker. Might evoke the
sense of abandonment that you're working towards here.
Or maybe not. Worth a shot, anyway.

I'll see what I can do. I got PVM to work on the computer here, so I'm
getting results much faster, but the radiosity is giving me trouble (part of
the reason I might skip it for this pic) We'll see.

Nice pic, bob. I like the bricks. However I would up the contrast a
bit further. Best way to do that is adjusting the black value in
'Levels'. And mayve it would add to realism to make the wet bricks
darker.

Thanks Mick,
I'll try the normal map tonight!
Really appreciate your help. I don't
know what I'd have without you.
Have a great day!

What I mean is, the trunk is both dark and in the
shadow of the tree. The grass and fence are
also in the shadow. Should we be able to discern
the trunk in the shadows? I thought so and was
trying to get the trunk to be at least somewhat
visible in the shadow, even if just a silhouette, but
it took alot of light and upping the ambient values
to get it to show up, that's when everything started
looking flat and washed out. I've reduced the ambient
values and now you really can't make out the tree
trunk anymore, but most of the other objects are looking
much better. So, as I get stronger shadows, the trunk
disappears into those shadows.
I don't mind that happening if it's considered the
appropriate view -- I just thought otherwise.
Thanks again!
