I did these sculpts some years ago (around 2014). They were made professionally as base models for a game. I needed to create different body types and took the chance to really practice my anatomy skills, so I spent a lot of time looking at reference photos, 3D scans and pouring through my anatomy book collection. All models were of course sculpted in a rigging friendly symmetrical pose, in these images I have just posed them a little more natural for display purposes.
