Last month we were running the 2nd CG Boost Challenge for 3D artists, with the topic "Ancient Robot". We received 180 entries, most of them made with the use of Blender. Since the main reason to participate on these challenges is to improve your skills, I have picked 7 submissions and created a feedback video on how I would improve these renders. I hope this will also help other artists to improve their artworks.
