Out of all the Source Engine Moe-Beings you've made, this one has the most plausibility to exist in the universe it is emulating.

It looks like Aperture tried to cache in on a Market involving Anime and thus, made something based on Their turret, but emulating the appearance of how most Anime would render a girl.

I like the addition of an extra eye on the upper torso, it implies the head is an Add-on, not necessary to function and that it's actually something similar to P-Body, with all the real essential components in the body while the head is little more than a case for 2 cameras and a speaker system like something you'd rig up to a computer.

Some nitpicks are relating to the humanoid eye and "mouth" as well as the inside of the upper torso.

For the eye, I wish that the eyelids were separate pieces of metal that physically slid via small mechanisms over the eye instead of being one piece with the face.

The eye itself could have been a ball camera rooted into a socket that had a wide circular aperture instead of an Oval.

Since the mouth is very obviously a print on, I think that the turrets should have fewer face plates encompassing only very basic faces meant for a role they are supposed to occupy.

Basic smile for possibly presentation where the turret is seen a lot

^ shaped frown to embody enemy turrets meant to be avoided.

D smile for possibly greeting people during an event Aperture would think one should be excited about.

The other 2 could possibly go since one is surprise and the other is another basic frown.

I'd also like it if the container in the upper torso was not an ammo box, but a black box meant to house critical components, since it isn't connected to anything and just looks like it serves as a convenient weak point more than it would actually function.

If I'd like to add anything totally new, it would be a third leg like the Combine Sentry Girl because let's face it, with feet like points, it ain't concievably walking without serious aid.

What do you think?
