This is Gaius, the 3rd Colossus you fight in Shadow of the Colossus.
Its silhouette has always been imprinted in my mind, so I decided to vector and animate it. I made a list of several videogames I wanted animated in 2D and this was the very first entry.
To vectorize it I used a still from the intro of the battle, then DUIK to rig the model.
