I was an Art Lead and Concept / 3D Artist for Sky Shepherd. Here are some concepts for the herd creatures and the predator that appears in the second level predator chase. The idea was to design the herd creatures to reflect their potential to follow the shepherd, while the predator is designed as a huge whale-like creature that potentially was supposed to just appear as an ominous silhouette or an imposing shadow.
