Well this is why it's called a challenge, and beginners work should but judged by the fact that they are new at it. If the idea of the challenge is to learn as well, then thats how it should be. When seasoned users are still importing things as the main part of the scene, which is something that could at least be attempted with Bryce modelling, well that ain't Bryce.
I'm no expert, what I learned, I learned by doing, and but seeing how others do it. There is simply no excuse why anyone cannot try to learn this way. When imports come into Bryce and those import play a large part in the scene, then it's no longer Bryce IMO. 
Maybe TheBrysters purist approach has rubbed off on me.
