Good Job! Nier Automata is one of my favorite games of all time.
I really admire how clean and tidied up your works look,
it really fits the ecchi, sexy, pinup kind of things you make.
I also like that you use a lot of negative space.
However I think that you should practice drawing anatomy more,
the way you render looks fine for now, whats really lacking is the foundation.
For example 2Bs torso is just one fat tree trunk kind of shape, which doesnt look feminine at all and this doesnt seem to be intended. The spine has an s-curve to it which is especially pronounced in women, so the lower back should be pushed more inwards, with the upper back and butt sticking out. Also the front part of her torso under the breasts seems to come out way too much. If it werent for these two issues, I would have rated it atleast a solid 3/5 stars.

Great work
