Looks slightly fatter. Getting fatter at the benefit of what, having higher polygons count? Nope, not interested. Definately not on THAT ship. And i am already fine with staring at it from afar anyway.
The old model used to have four turret mounts on its top and two on its belly. The new model, somehow, seems to have hell of a lot of those. For what purpose, other than cosmetic one? Looks rather excessive to me. You might or might not want to fix that, depending on what it actually is.
Also, the old one has CM and minedropper mounting points shifted more to the belly. The new model has those shifted more to the sides. Which, to my taste, looks better. But, given the CM and minedropper model sizes, won't it cause hitboxes/textures overlap?
If anything, IMO, better add more lights for pimpship. Or animated external cargo pods. Or, finally, codename fighter turrets. Other than that - somewhat pretty, i must commend you for your modeling skills. Not bad at all.
