Cataphract Robot With Firestorm Cannon

Regarding my Legio Cybernetica Kill Team this one is by far my favourite as he looks like he's ready to take on any opponent, sadly that menacing look will likely cause him to attract at lot of enemy fire.

'Firestorm Loadout'
I have given this robot the 'Torrent' special rule for the Kill Team tournament and yes this is legal. I've also added a shoulder mounted flamer for the bolter's template, but best of all I converted this awesomely destructive weapon I call 'The Firestorm Cannon' which destroys everything is fires upon however it suffers from a long recharge time so it can only be fired once per game (i.e the metlagun's torrent shot).
