Modelling Practice - BZD Rifle

I just felt like sharing with you my rifle high poly based on Dmitry Belozorov's concept (https://www.artstation.com/artwork/0y43Y).
I'm going to turn this into a fully retopologyzed, textured an functional game asset later, but for now I'll just leave it thrown on some differently colored metals to get some sort of idea how I might setup the weapon.
