Looking really good so far I agree with the others, she does need a lil sprucing up!
Model wise, they all look really cool imo, texture wise I think maybe you could add a bit more detail on the uvmaps, although it may be the cartoony like style you are going for, so ill shutup!
maybe have the clothes bit less bland? or maybe 1/2 coloured, 1/2 worn down to that dull colour?
hope it helps, keep up the good work!
