Wow I really like this, I've been gone longer than I thought!
#4 looks so much more feminine now, and green really brings out the blonde hair, maybe desaturate it a bit so it blends with the more grayish tone of the rest of the crew. If the green still looks like too much I would suggest either coloring one item (pants/top) gray(or some other neutral color) or lighten the item on her hips to a med/light gray color, it might help make the green look less intense after you desaturate it.
I like that high shoe/puffy pants transition you got going on with #3, what if you did that to #4 to show a bit more leg? It could be tricky, it could be easy just throwing it out there.
The suspenders look alright on #2, though I think they would be more stretching against his belly, they seem pretty slack to be holding up his pants.
I did like the coat but the suspenders made him look like a good guy while the coat made him look like a badass good guy or a bad guy.
Is that fire that #3 has? I think someone mentioned before you'd want to make it look more like light reflecting and not like he spilled wine on his clothes and face. But I can't remember if you said anything about that and I'm too lazy to double check.
