Burghers (not burgers)

I'm really hungry - hence the burger digression. The ones with an 'h', though inedible, are far more interesting to draw. Rodin's famous sculpture is right next to my  work and I'm going to try (once this horrid weather sorts itself out) to draw the Burghers in my lunch break instead of reading anodyne and instantly forgettable novels. Here is my first attempt from yesterday. It's unfinished because my hands got too cold.
