I really like the muddy ground. However your texturing for the gun and the concrete can be improved greatly. The gun from what I can see only has scratches. The concrete has those lines that go horizontal which take away from the entire piece.
@3dReaper I just decided to take it off, it was an older asset. @Joshschmitt & @_Kratos_ I have already gotten critiqued on the gun texture and need to update it badly -_-, poor time management on my part, I will also redo the concrete texture as well. Thanks for the crits guys!
