My 2nd entry is named Art gallery:
" 'Think about it' - is the art exhibition that leaves no one cold. You are encouraged to ponder your value in society - are you an object - a consumer - or a divine being of infinite worth?"
- All done by me for this purpose in Blender (basemesh for models in art exported from Makehuman and then tweaked)
- trees made with sappling
- 6000 passes in Cycles (left it rolling overnight after several drafts)
- mostly post-processed in Blender
- slight levels fix and sharpen in Photoshop
