Painting him was really quite straightforward, brown with a wash and dry-brush, then add detail. I've tried to add some globules of clay on his base as if they've fallen off his body by using greenstuff, but i'm not sure of they're too regular or just look like the area he's passing through is used by dog walkers.
I'm not overly hopeful of victory because not only am I still learning the game, but the rules (naturally) forbid any of my cheaphammer shenanigans and so I've been forced to cobble together a crew from my official miniatures. Even I can spot the tactical holes in my force and so I expect others to exploit this mercilessly. Fortunately, this event is using the Swiss system, so after a couple of games I should have found my level and may stand a chance of winning a game.
I'm going to try to take some pictures and put together a tournament report next week, so watch this space.
