Day 2 works well as a layered soundscape, meaning that all three mp3's can play at the same time to create a soundscape: Someone is outside sawing in the breeze, and a bug is clicking nearby. Perfect. Day 1 rides the fence. On the one hand, we're not concerned about quality. On the other, it's a far stretch to imagine a scenario where there is hammering, birds, and driving in a car: A guy driving in a car, transporting a portal, through which we see another guy hammering by some birds. So, I'll pass it, but going forward, it's appreciated if the layers make a soundscape.
