Here is the new Skitarii "sentinel" taking shape. Besides copious amounts of greenstuffing required to hide gaps this will be fitted with twin plasma cannons (thanks again to the tau - this case from the FW hammerhead upgrade for plasma cannons). I've decided that it will most definitely not be fitted with tracks. My favourite bit happens to be the screen area through which the skitarius sees the world (it will have a domed screen in the centre). The bases of a tau drone was cut off absent mindedly to find it was the perfect size.
