...much better smile kind of "I don't care whatever happens", hard to find same for Cloud, dunno why people draw him mostly as badass or sweet pink little Aerith kisser. In game he's taking everything cool for most of the time.
I believe the word you are looking for is 'smirk.' I wouldn't be opposed to a smirk option, but the problem is that whatever TA gives him will be there for
every moment of the game. Considering one of the only times his face is front and centre is at the end of Disc 1, I don't know if giving him an expression at all is going to be helpful. In my opinion, the more neutral, the better. Anything but the PCs default inksmudge-mouth.
Also, great work guys! Don't let us rush you. I will wait forever for this. I will
cure old age so that I can wait for this.
