Soooo much fun to draw. I added/changed a few minor things from her original picture and tah-dah~ Cute. She is mainly bipedal!

The reason for the almost humanoid body.
Her kind, a type of parasite, attach themselves to a host and once mattered, they just take over. They look like their mother species, but vary upon the host. This one here was attached to a female human. It's very rare for one of these parasite to even survive to mature and take over, but when they do, they will live for years to come.

Sadly, most if not all, will have no memory of being attached to their host and once they have matured and taken over the host it's almost like being born and coming to in existence.

Egg>Parasite>Attached to host>Matures and takes over>Make offspring>Repeat Most of the time, they do not know they are creating parasites as their kind are so rare and usually are killed before maturing.

Though they are more of a parasitic alien, some can be very friendly!
