I definitely would like to see tutorials written by extremely experienced artists and/or Bryce people, where you get to practice a particular set of techniques with the goal of achieving a particular useful end in mind, like you say, a white oak that looks like a white oak... Or using meatballs to create breakers... I mean, you can always look in the manual to find out how certain things in the program work, but you need to see how other people with more experience are doing certain things, so you can grow by doing things that you would never figure out on your own... At this point in time, there are a lot of tutorials out in the web, the Peter Sharpe site comes to mind, Brycetech, etc... Even some of the tutorials you mention can be done better... so ,the question is, who would write said tutorials, if it falls outside the scope of our experience? anyway, my vote for a tutorial goes for making really convincing breakers in bryce, and don't direct me to tutorials out there cause they don't cut it... :)
