will there be any use of vray in the rendering again Dave, similar to the recent interior modelling tut?
above renders look great.
im surprised by the 'rational' use of the sp paint script, if its the same as the one ive used before, i thought it was used for fairly 'uncontrollably' placing items like rocks and grass.
sppaint is good for 'rational' placement as well, although i mostly use if for plonking down a bunches of instanced trees, bushes, rocks and that sort of thing.
Mental ray will be up first, vray I'm not sure I might if i get the time 
Glad you liked the renders
