The problem with this, is how Xenos lack real resources and manpower to actually grow, not to mention produce/operate capital ships, they are radical terrorists who are not that numerous, therefore it's hard to decide what their "Shipline" should be, or not to mention if they could afford building their own, with tools they don't really have.
RP factors aside, this model sure would fit the Xeno theme, and would give a clear distinction from the other surrounding factions, yeah.
And as I already told Lucas, this is a very good modelling work right there Kudos again!
