Dude, that is the most amazing thing i've ever seen! I hate to criticize such a beautiful piece of work, however skaven tend not to carry swords like that, they don't swing back with blades. they stab or swing the blade forward. Again beautiful work and that's the only flaw i see
When I started drawing this I looked at the Packmaster models that come with the Rat Ogre box set. ---> [link] The one in the middle is carrying a similar shaped blade in the same manner of my drawing, with the blade facing toward the elbow.
