My 'Search For A Star 2020 - Game Animation' submission, using Game Anim's 'Azri' rig (https://www.gameanim.com/product/azri...). The work was hand-keyed in Autodesk Maya and is presented both as Arnold renders and in the Unreal Engine. The entire sequence, as well as the initial 'idle' segment, seamlessly loops.
