Wow great concept. Excited to see the final Render. 

All the Assets  are made  for this contest is newly created, ZBrush Female Character used as starting point Only face I have change to match with my concept. Edited same female character and made robot model. For blocking I used Maya and later all the model detailng shading and rendering done in Blender. All other props are created in blender. All tileable textures are created in substance designer. For fabrics and wall I used downloaded alphas then generated details in Designer. Other texture are done in Substance Painter. Used photoshop for making image collages. Main render is taken from Blender and slightly adjusted the contrast in Photoshop. Additional render taken from Substance painter and adjusted contrast in Photoshop.  Hope you Like it, Thanks for reading this comment

This render is very nice on multiple levels.

Nope.
