The stanchions of the main guns need more detail likewise all the front armour on the carapace and main hull. The under carapace detail windows and access panels to view the interior, the interior of all three decks and the cockpit, leg hydraulics, spaced armour on the greaves............ The list seems endless.............. Oh, the shoulder mounted twin turbolasers and the lighting.
