Coool! Tres Coool!!! This is shaping up to be a terrific image! I wouldn't bother too much about size if I were you (unless RAM is a problem), 'cos my images quickly move to over 300-400 MB with ease! That's how Bryce works! C'est la vie I suppose! :( But don't sacrifice size for the beauty which is inherent to the image you are doing!!! Have a suggestion, how about doing the terrain on which the toadstools are in metaballs? That way you might get a real interesting terrain and something closer to original!
