it takes time and practice. Think of it like sculpture-- you'd laugh at someone if they asked you "if I buy this chisel, will that make me a good sculptor?" It is not the tools, its the eye, the experience, and the vision. I'm always blown away by what people manage to do in Bryce --which has a very limited modeller. As I noted above, I also like Amorphium. . .fun and easy. For getting started fast on landscapes, Vue d'Esprit is excellent-- you'll be producing things you like in half an hour. . . In general, the people who do the really good work, the stuff you admire and want to emulate, are working a couple of hours a day on modelling-- that's why they're good.
