I think this would be really well done if the models were slightly different. TBH probably a 2/5 for me as is, but could go up if models get tweaked. I think all of them could use a little work, but the main characters face, I just can't get over it. It almost looks like you took the toon model's head and applied it to a normal model's body and reshaped it.
Face is unnaturally too smooth with strange cheek structures. I was hoping the blonde that you use for the background in the options menu was the main character, since he's all over the place image wise, but looking at him again, maybe the overall size of his head is slightly too small. The proportionality seems fine, just the scaling is off I think same thing with Axel, some scenes, maybe it's the angle of the camera but his face looks disproportionate. I won't even go into Sawyer, I'm sure this is an unpopular opinion, but I'd rather just pretend he not exist.
Finally PSA to all Renpy devs: Stop removing the skipping option. Just stop. We know it's a Renpy game, you can do your custom options menu, but stop purposefully removing options from the game. It literally does nothing, except adding extra steps for me the player to then go in with UnRen and undo whatever changes have been made; sometimes I don't even use it, whether or not I use the option is irrelevant, I just like having the choice to use it. Stop removing the choice to skip through stuff.
