Some very nice improvements are coming for Tree Studio 2.0. Among them will be a tropical tree ArtSet with Palm trees here is a quick look of one that is still in development.
Also a very nice improvement will be scaleable trees. Change the size of the brush and your tree is smaller or bigger. Along with that will be allowing bigger page sizes.
There will be other additions and improvements too.
Sounds good Ken. I can't draw trees for nuts... :)
