Awesome demo, see all the hard work you have put into it. My only advise/critique and it is something happens in most games is the blank stare what we do in real life aka our resting bitch faces hehe.
The thing is with 3DCG models it makes them look lifeless for example the difference between intr28.jpg and intr29.jpg. That open mouth with open eyes intr29 vs just the slightest of smiles you've added in intr28 makes the difference between warmth and soul-less.
I know we have blank expressions in real life, but when it's on a CG Model it makes it cold for example intra35 vs 36 vs 37, 36 is the coldest of the three. The in car face close ups are amazingly warm renders awesome job on those.
Another example would be the following scene at the the school lobby: intr46 is awesome cause she is looking at the screen, but once we start talking to her, the blank expression with zero smile gives that cold doll like feeling. I'm pretty sure if it was a face closeup it would be warm and fine, but because its a zoomed out model render, it comes of emotionless and cold.
I know you are thinking but every other game designer does this too, but I feel as you are on the ground floor for your game, I want you have the warmest lifelike renders around and change the game standard for the better.
Even with scenes like intr57.jpg with amazing eye contact and scene direction, the blank expression will happen in real life during a conversation, but this being a static snapshot adding tiny smile / laugh / grin will make it feel warmer and more realistic case and point Intra79 and 80 feels warm cause you can sense the warmth of the models.
The locker room models feel a lot warmer (soulful) than the coffee/beak room models.
Does Mrs.Smith model have the same facial expression render in intr121 vs intr125, if that is the case then its just close/far the model's face is in the scene. Cause 121 is normal and warm and 125 has the doll effect. If that's the case then if its not too hard to do, exaggerate the facial expressions for non close up models.
End Rant. Please note I love the demo. I followed and read through the entire thread, so I really appreciate all the hard work and time you put into this and I really want you to have the best game that reflects your dedication.
