I know its not perfect , just a fun project 
Yes I did the motion blur with Aftereffects in post.
I am using C4d Octane 3.08 course I have Hair Render problems with 4 and Denoiser.

Iclone rendered 10 min , Octane did 1 hour and 40 min  with 2 GTX 1080s

Really having fun with IClones animation possibilities.  :-)

P.s.  It took about 5min to bring all to C4d ... ( just push the Octane Texture converter button) , the only thing you have to manage is hair and eyebrows. But thats only an Alpha invert problem.
Hope I could help ;-)
P.s2 , the Iceberg is flickering, that was my fault using no textures at all , its a model from sketchfab with bad normals.
