Actually, I’d say that it might be too good to be put inside an FPS game. A game that involves guns might fit better, like how Notoriety works.
The gun in the bottom row, in the middle: the handle is a bit bland. Try adding a bit more handle stripes to it.
There isnt a Sturmgewehr-44 on there. You must have confused the MP5 for it.
Its the bolt of the UZI, the background colour matches quite well with the top of the receiver on the UZI
Pretty good gun models, I can see the large amounts of effort put into them
I like the way you made them they look really nice and well detailed
