yup, didnt refresh, answering:
1- Since i dont have info on it, i took as a base the syringe was to take blood or whathever samples, or inject drugs or nanos..., so making the vials bigger was not neccesary (you are getting a bit not half a litre).
Regarding the handle, i think it is good, just look at the hands of the sectoid/grey alien, it fits there nicely.
A needle really doesnt need any strenght to pierce, and this piece of equipment seems more rigth into the hands of a medic or scientific than an alien soldier.
2- I agree with you, im not really happy with the body either, perhaps making it a bit wider and adding some tubes will both make it more alien-like and interesting.
About poli count, ill try to discover it
