Part of the reason that there's more stuff (some of it really wonderful) by Brycers on display may be because it's a good program for what it does: landscapecentric still pictures. However, part of Carrara's mission is to be an animation studio, thus it makes sense that fewer still pictures would be posted. Also Carrara has a steeper learning curve. I love Bryce, and as a hobbyist, prefer it for outdoor stuff. As much as C3 adds more for landscaping, Bryce is still better for that, unless you're looking to animate. But Carrara will take you further on everything else, especially with its newest features, like HDRI. I suspect as people digest the new version of Carrara there will be more and better pics posted. But in the end it's not a Bryce versus Carrara thing, great pictures are where you find them, whether on Bryce, Carrara or any other app.
