I've finally gotten around to finishing this for a second time through, as my first time was simply to watch it without taking notes.
Here is the very small list of what I've come up with:
-maybe include a scene at the beginning with someone explaining to Rick what has happened. Once he makes his way out of the tank and meets the group, he seems to all of a sudden just know that there has been a zombie apocalypse and that most people are dead. We can simply assume that this is crazy obvious, since the streets are deserted and everyone is going berzerk on killing zombies. But if a scene exists where, maybe Glen, explains to Rick what's happened while he was coma'd out, would explain a lot.
-there seems to be two early cuts that are off a bit, somehow. One is where Rick is introduced to the group back at the quarry and then it cuts to the campfire scene. I think this one has been addressed in comments above, so I'm sure you're fixing'er up. The other seems to be when Shane is about to shoot Rick and says the deal about wearing reflective vests, it then cuts to a scene with Shane speaking to Rick. Something seems off about this part, like they were just hunting and are now somewhere else right away.
What I did love was some of the great editing. I loved the fast paced editing of the scene where everyone is hiding under cars and Andrea and Daryl are killing walkers at the same time. The back and forth between Andrea and Daryl is super and definitely gets some adrenaline pumping. As stated in previous posts, the audio and video editing is near flawless, very nice work.
Can't wait to see the final product. I do agree with above posters that a new opening credits and title would work really well, but I personally wouldn't want to see something like "Night of the walking dead", I'd be expecting a Romero/TWD crossover with something like that, but that's just my opinion. I liked your idea of TWD:Forsaken, or something similar.
Enjoy the editing, like I said, can't wait to see a final!
