Some old art of my "dinosaur-human coexistence" concept, featuring characters OTHER than the protagonists!
These characters are Maria and her son Davey. They run an inn that Ben sometimes stays in during his travels. Maria's companion is a Tetrapodophis named Fourfeet and Davey's is a Rahonavis named Cloudy, whom he's trying to teach how to talk.
The next pair are Ren (blue hair and pronouns) and Irwin (blond hair). Ren is a person living on an island to the east of the continent working to become a veterinarian. They actually become Ben's love interest when he and Windryder crash land in front of their family's home. Their companion is a Leptoceratops. Irwin is a boy who lives on an island to the west of the continent and he and Ben get wrapped up in an adventure involving pirates. His companion is an elasmosaur named Nessarose.
These two are Alon and Typhoon. Alon is Ben's grandfather and a fisherman who trains pterosaurs to fish with him like cormorants. His main pterosaur is Typhoon, an albino pteranodontid (originally meant to just straight up be a Pteranodon, but I'm thinking of changing him to a Tethydraco) who's been with him for nearly forty years.
And this image is just a better picture of Ren, since I feel like the one with their Leptoceratops friend didn't show enough detail.
All these characters belong to me!
