Yeah I thought about doing that, but some of the girls I'm using have some of my favorite scenes with actors who have dramatically different bodies. I'd rather have the best scenes for each girl even if it means in one scene the MC is a bald guy with a bodybuilder physique and in the next shot he looks like a scrawny teenager with a full head of hair.Generally for the player I have been cropping images to not show their face.
Using videos I have generally tried to use POV style ones or crop the video to again hide the face. This though is a question of the nature of the scenes wanted, A Spell For All just uses short loops up to 30 seconds mostly much shorter
Cutting the face out wouldn't be enough to matter for scenes like that. So I don't really care if the MC looks like Jonny Sins in one scene and Danny D in the next scene. What I care about is that he's fucking Madison Ivy and Shawna Lenee rather than whatever random girls I can find videos of the same guy fucking. Either way it's a concession.
