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.
Now all we have do is wait for a war machine to explode, the rats to panic, eat their pack master and then turn about and go into a frenzy in perfect Skaven fashion. The pack master looks like a true member of Clan Moulder, the ram shackle armor, patch work clothes, bandages, cuts and markings of the clan all add together to create a beautiful piece. The flood of rats making the ground is a very neat, interesting touch, a consistent theme with the skaven.
