Alright, for this image I think I pulled out of blender almost everything I knew. From SSS and fluid dynamics to using HDRI with the open EXR file format.
This project was done in a digital class where we students were creating 3D exquisite corpses (really cool idea!) I went a bit overboard with my head piece.
The original file was rendered for a print resolution of 240 dpi at 16x22 inches. File sizes and rendering times tend to balloon at these resolutions.
Just for fun, here is a 75% zoom detail! yay!
(its slightly blurry because of the DOF)
Hope you all enjoy!
