I was very impressed with the first chapter of The Silver Lining. However, one thing made me wince every time I saw it:

It seems like some of the lipsync (mostly during words like "our") during Graham's closeups are overemphasized to the point where he just looks unnatural and ridiculous. The big problem is that Graham is showing too many teeth. Try making sounds like "our" with your own mouth and you'll see that while your mouth is shaped very tall like Graham's, your lips are covering most, if not all, of your teeth. If the picture above didn't show his teeth, it would look much better and more natural.
I don't know how much control the team has over lipsync, but I'd really be obliged it if future chapters would make Graham show less teeth when he makes certain lip motions. I assume that eventually a version 1.1 of Chapter 1 will come out to fix any bugs and such, and I would also hope that this would be fixed too.
