-Marduk-style intake tubes between the wings/fins/leafs
-Added detail to the front/mouth/forward gun area
-Add skeletal structure inside the ship
Then we'd have something workable I think.
Overall I think it's a good design, and I like how the whole thing looks like one giant cannon - exactly what I was aiming for with a smaller version of the nomad suncrusher. It also fits the long range siege weapon role of cruisers in disco.
Now if we could just get a response back from mjolnir on adding a nomad cruiser forward gun for 4.86...
EDIT:
Luis, suggestion on the wings/fins/leafs, though - currently you have the 'notches' in them shaped like a V, whereas it should be shaped more like a U. Refer the nomad bomber in the proposed images on page 1. The wings/fins/leafs could also stand to be a bit wider.
