Hello! As I do only the programming behind the game as well as most of the pixel art, I am not certain how Vlision, the artist who works with me makes the renders. From what he has told me I assume, he has a morph for the body and for faces he uses premade ones as base, then changes them up a little to fit the character. I will ask him and add another comment if there is a difference from what I have mentioned, but as he is a bit busy lately, I don't know when that will be. Hope this answers your question at least a little!
