Miles Hellyer shared a quite inspiring 3D project titled Ceramic Therapy. The reason I say that is because it’s a simple example of working with 3D. Not hyper realistic or crazy renders.
Diego Maricato shared an incredible image as part of the 3D course he was taking at the Unhide School. Gudetama is a self-study project applying the knowledge and skills acquired during the course, from digital sculpture with Zbrush to texturing and rendering with Cinema 4D. The idea was to take a different approach from what the instructor took. The result is quite amazing, check it out.
