...if nothing else- you can find some more nice brushes in the Piranesi demo!

Plus- the Piranesi gallery renders are good targets to aim at. I look at them and think: How could I do this with the Carrara NPR brushes?

Another interesting idea that Piranesi employs are people cut-outs. I think that this is something that could be tried in Carrara- there are some cut-outs included with the Piranesi demo materials.Somewhere I saw some Carrara examples of how 2D images were made into 3D cutouts. These would work nicely for Architectural renders...

Actually- I just had an interesting idea to try! You can take Poser characters and Z-Flatten them!You can, of course, do this in Carrara as well--- so you could have Z-Flattened people, trees, etc- and they would look very "artsy" for a sketch style render with NPR brushes!  --I'll have to go an try this!
