Interesting development. The color difference between the assistants (?) and the General are quite nice.
Front shots are a bit hard but the feet on the male assistant look a bit "flat", a line indicating where his ankle and foot meet could help create depth as would some creases on the sash around his waist.
*on the last page, you might want to be careful about how you shade under her hair, it's a bit dark and creates the illusion of greater distance than you probably intend.
EDIT: And oof, your classes, hope you find some time to relax!
