Well, you also need to call yourself a furry. You can be interested in them and not be a furry at all. It just depends on how you're interested in them.
I've always liked the design of the character tees more than humanoid ones. I feel it gives a bit more flexibility to design, opening many possibilites
Yeah, but you have more freedom as you can change the type of animal, which changes appearance. You could have a wolf, ape, dragon, etc, and they all look special. With human it's really just skin tone and minor details
Well, it's sort of a furry's "identity" in he furry fandom. Basically a fursona is an anthropomorphic animal character made to represent someone. Sketch is mine.
