As a social media experiment I labeled one of these gorilla sketches as “gorilla Grodd” on Instagram. It got more likes, even though the sketch was just another gorilla head study like all the others. That one got more likes, because the perception of it as a known character somehow adds more interest to it, even though the sketch isn’t any different than any other gorilla sketch. In fact, Grodd is just a super-gorilla, but design wise he really is just a gorilla.
I have no conclusions, just something I find interesting.
