Hello.
First of all, thanks a lot for making the technology preview available to the public. Terragen is an amazing piece of software and this second version is much more powerful than the previous one.
I really like the new features and the idea of a node based interface, although I would like to have more features, like the ability to enter expressions using environmental variables.
The preview window is useful and very accurate and the fact that it's recorded in 3D and that you can move tha camera once it's generated is very cool, although I would like to have the possibility of visualizing a low resolution wireframe of the scene for fast camera placing.
The clouds are very realistic, but when "zooming out" and viewing the planet from the space, the repetitive fractal patterns can be seen. It would be very nice if the cloud masses would form some realistic shapes when viewed from space, blending between different fractal algorithms between "planetary level" to "close up".
As for the object populations, it would be nice to have the possibility of visualizing then as shaded boxes instead of wireframe to get a better idea of distribution. I also think that the grass can be very difficult to set up, because is not easy to see the scale in the viewport and the results can be different than expected, but I have to do more tests.
These are the first things that came to my mind after playing with it a couple days.
Here are some renders I produced.
