Hey Daniel,
Did you post in the wrong section? Maybe the mods will move this over to the critiques/posting section? Either way, my two cents:
What color space did you use for these? In my browser (Google Chrome), the majority of the pics seem adequately lighted, but with really cold white balance. The few in the middle (after the girl with the crazy eyes) seem properly white balanced. The rest look as if they need to be warmed up, as they have this cool (blue) hue to them. Many of the shadows are a distractingly blue color as well. If it's not my browser - an hour in PP with this should clean them right up, though.
Test with an attempt at warmer WB:
