Hi,
I finally managed to submit my finalised renders to the artstation contest.
https://www.artstation.com/contests/nvidia-metropia-2042/challenges/62/submissions/42091
It took a while to get to this stage as I worked on it 1-2 hours a day, sometimes less than that but as expected, Blender manages to do it all.
These renders were made in Blender 2.8, Cycles. Apart from some other softwares that were involved in some of the assets creation, it was all made in Blender, rendered in Blender, composited in Blender and so on.
What can I say… best software ever!
Hope you like it 
Thanks!
