The second and third are my favorite but they are all pretty good. I do not really like the fourth one's hair though.
So for the second, I was really wanting there to be no dark colors, it is sometimes kinda hard to do though, and I though I adore the hair I would like something different because I JUST sold that item a week ago (my bad, shoulda kept it). Something similar with maybe some green would be PERFECT for that. The hoodie in there is perfect perfect (I adore hoodies but I didn't realize they had hoodie items') It is probably going to be kept in mind

The third one is more up my ally for the dark area,though I would rather it be less flashy, more black and any red to be closer to the hair color. Maybe an avatar with pants? I haven;t managed to make a cute one with pants in forever. I like somewhat simple and more down-to-earth adorableness.
Oh, I feel like I am being too picky for something that is free :/
