The only thing I think at this late point is you might want to upsample the HF a bit. The mountains are a tad too... sharp edged. What is the resolution on your HF now? The default is, I think 256x256. From the look of it, if you did this all with one terrain object, it would have to be at least 1024sq. As a rule, I tend to use 2048 resolution in bryce, but for a big image, you might want to splurge on 4096. I wouldn't say that for a screen image, but if your going for an overnight render, it might be worth it. On the happy end B7 seems to render much faster than 5 and 6 ever did. Just a C&C for what it's worth. In any case it's a lovely job. Good on ya mate!
