I haven't played the demo yet so I'll update afterwards, but just wanted to give some feedback on the protag model. This could just be me, but the way the cleavage is drawn seems very off.
The character itself looks fantastic and is great for the protagonist (like Claire and Natasha from their respective games), but I think the cleavage is missing a line on (our left, character's right) breast which makes it seem unnatural and really off compared to the other one.
I think making the line more of a Y (branching line) instead of a simple curve would "fix" it? At first I thought the sternal bone (not the clavicles), but that's actually fine I think.
