My first untextured 3D modelling assignment at Uni. I based this model off a cool watermill illustration/concept by Alexey Serebryakov. < https://www.pinterest.nz/pin/830280881284931586/ >
In hindsight I should have picked something more predictable. After modelling the visible 2 sides of the structure it took me a while to make up the other sides on the fly. I just loved the look and feel of the concept so much. Fun project. Not so fun 4+ sided polygons and double extrudes.. It was a long night.
