Apparently he.s a professional animator, and Genndy Tartakovsky's Primal was one of his main influences for the look and aesthetic he chose for this. It looks to be part of a pitch package he made to shop to his agent to see if there is interest among distributors/streamers/license holders for him to lead a Conan animated project in that style. He says if he sticks to original REH stories and and uses story titles instead of Conan in the name, he can use the public domain status to do It without having to license it, but he would prefer to work with the license holder (Heroic Signature but he never mentions them by name). I didn't see any of that before I saw the clip and shared it, as it was from an earlier post leading up to his posting the clip, and I wasn't following him until I saw the clip (which I saw because it was reposted by Stygian Dogs, a you tubeer who does a lot of S&S themed content that I follow).
