Some good exploration here. Watch out for the heads getting too large generally. It gives a more cartoon look or makes the characters look more childlike, which may not be what you want (except for very young characters like Luet). Some parts of the silhouettes would have to be "figured out" as to what type of costume piece would create that shape, but it's valuable just to explore the shapes. On the first sheet (Luet) some of them read as masculine, maybe due to shoulder width.
