Quote - Offered as freebies is very appealing.  Have you considered rendering alien landscape or fantasy versions?

Yes, definitely... personally I am into a lot of retro sci fi stuff, as found in the likes of "Fantastic Stories" periodicals et al.

This book is a major resource for me in terms of that:

In terms of Fantasy... well, I'm a big Rodney Matthews fan. Would that sort of thing be in order on that front perhaps?

Both these genres may need to wait till I've saved up and added the Botanicals module to my Vue stack though... so I can try and make up some alien / fantasy plant life, in the style of JC (James Cameron). LOL. 

Or maybe just accrued a bit more ready-made Vue content in those genres...

But sounds like a good ultimate aim ;-)
