Some older sketches and drawings that I forgot to put here earlier.
Designing gryphons for a personal project, based on the premise that they're small fire-less relatives of true dragons and tend towards scavenger behavior. For my world building purposes I don't necessarily require them to be immediately recognizable as gryphons/griffins, but need them to look like a creature that could have inspired them.
As dragon relatives, their wings are bat-like, and rather than fur their bodies are covered with rudimentary feathers, something similar to what therapod dinosaurs would gallivant around in or what modern day ratites wear.
Reference! Mostly stuck to vultures but there's some fish in there for flavor.
Did these silhouettes later after already finding my general look and feel. Just narrowing down little things like overall proportions and wing shape.
