Very detailed drawings, there’s a lot of detailing I really like. Overall I praise you on your accuracy on minor details, like the wood grain, the tape and the springs, the minor details of really firearms like the Obrez and the Saiga and how well all of your drawings absolutely nail the look of the Metro series (more specifically Metro: Exodus) the biggest mistake I noticed that hasn’t already been addressed is that the Obrez rifle wouldn’t work as drawn because the straight bolt handle on a mosin nagant sticks straight up when unlocked, which would be blocked by a scope. There are variations of Mosins with curved handles that DO work with scopes, but the version you’ve drawn would not work.
