Nice work for the teamcolor !
about your marine :
Nice ! Definitivly looks bigger than Guauss Rifle.
Maybe you should it a bit different so that it's a little bit more noticiable. I'd suggest putting an epic scope on top of it !
edit : in fact they're good the way they are actually !
I hope you give some teamwork color for the model so people can use it in multiplayer game.
I've seen your Kerrigan model. I finally realised the shiny parts get teamcolored : that's neat stuff !
