I had the idea to depict my sona Saur relaxing whilst in his default Rex form. I was really debating whether to have him in a bathtub or a pool and eventually settled with the former, based directly off of a drawing of a big, beefy Exveemon I saw on e621 and Twatter/EXema.
I did alter Saur's feathers based on the previous depiction of his Utahraptor form and after seeing anthro Rexes on FurAffinity and e621. I did want to draw a thicker feather mane around his neck but unfortunately, I forgot to include that. Also, the rubber ducky I based off of Evander in Amber Isle.
