In most cases I would agree about the tone of the flesh but it seems to be a part of your signature... simply wonderful. Iwould like to hear some of the back stories about you and your friends while shooting :-) bet its a neat group.
Can you turn on a few of the firetrucks emergency lights in post? That is the only thing I see missing, besides I'd like to see a bit of a warm hue to the faces to make it match the scene a bit more.
