I guess I could scale up the floating panels a bit more. Make them cover a greater area. The scale of the pipes is a bit off, too. The actual model has smaller pipes, and I'm pretty sure most of the dark part is just hull painted dark grey with small pieces of stuff glued on. I'm hoping that the bigger pipes will be able to capture the same space, but in a more visually interesting way by exposing the interior a bit more.
Form over function, it'll look okay, but I don't think it'll make a lot of sense from a functional standpoint. If I were a Mon Calamarian engineer, I'd be building blisterless ovoid, with ridiculously thick armour and a few really powerful weapons in the front. The back would be all engines and it could just power around blasting stuff before running away. That would be really boring aesthetically, which is why Star Wars has greebles and missing armour.
