Hey Meriba, sorry for the long delay. I have messed with some more dispersed trees before. Sometimes it looks good, sometimes not. It certainly is much more time consuming to do whole forests that way. Perhaps I will revisit that style. I like the example you posted. It is nicer in full color. In B/W I don't think it would convey as well.

Vellum, I think I answered you elsewhere but if not then - yes, it should work in CS3.
