I suppose you are referring to this post he made? It does seem like he has worked on a Bayek cosplay, but at the moment he has not published the photos on his Tumblr and DA. I am assuming that his fans who support his Patreon page are the ones who would be able to see them first (in fact, if you look at his Patreon there are patron-only posts, one of which is about a WIP on Bayek).
I personally adore his Gladiolus cosplay (with his DMC3 Dante being a close second). 😉
