Firstly - nice model with loads of character!
Secondly - I feel like I’m not entering into the spirit of the thing with this, but - the sward on the back… It looks like it would be too heavy to wield, it doesn’t have any sharp edges, if the blades were sharp, they would be cutting through the ropes, and it could hardly be drawn quickly in an emergency. I feel that these are really nit-picky, as it’s pretty much the sword that makes you know it’s post-apocalyptic, so I’d understand if you went “stop taking everything so literally! It’s stylish! Levels of realism!” … a scabbard would solve a lot of these problems as well.
