Early screenshots of rebooted version

As mentioned before, I started from scratch after a year and the new version is being created using Side Effect's Houdini. I'm using the free Apprentice version at home so the renders are limited in resolution and there is a huge watermark on the bottom right corner:

Shadowed side of clouds and terrain are always too dark

Terminator red zone too wide and unnatural looking

 

Landmasses too dark, sun glint is too broad

Images are dated 30 Aug 2011. Still a long way to go at this juncture...
