Thank you for the feedback!
I try to differentiate the faces through eye, nose and slight changes with the cheek shape. But id say the main culprit causing a slight same face syndrome is the lighting style Is practically the same for all of them. Aswell as the very limited posing for the head in general.
It's something id like to improve upon in my later projects. But for right now i feel it gets the job done.
Glad you enjoy the game so far tho! And thanks again gor leaving a comment!
