1-good color, good exposure
2-very green undercurrent in the fleshtones
3-a bit weak in the saturation and color department
4-back to that odd greenish undercurrent
I wish every single one of these had been framed as verticals.
I am going to agree with Derrel here on color and exposure, he's already said it. Although sometimes I too like the horizontal shots when I am trying to illustrate surroundings. Super cute girls. I dont notice much grain either but could be me.
