I always use Terragen for my landscapes etc, but I do like to dip into Blender as well. Here's my current piece (I'm a Doctor Who fan. The TARDIS dimensions and colours are based on the original 1963 prop. Tried some volumetric fog. I think the Black and White works better. For those not in the Know the sign saying Totters lane is in reference to the location of the Junk yard the TARDIS was first seen.
Hope you like them
