This is the outfits from the main character of our upcoming game Project Human. Is there anything that should be improved on this character.

I mostly like them, but I would like to hear some other people opinions of them.

Well it looks nice. 

They look nice so far!
I would have to say that you might consider making the eyes further apart as the whites are not easily picked up by eye, the black skinned sprite looks a bit more readable in the face.
I would also really suggest adding a layer or two of shading as it looks very flat right now.
