I stand even more firmly behind my previous statement,
Shivan != smooth rounded shapes.
make it MUCH more angular and less like something alive and natural, there should be unevenness and blockyness, but this looks like a fish (we all know who wuvs fishes), it should look like the antithesis of life.
and no bolts, Shivans have never had bolts.
now the thing is, the first draft of this thing was very Shivan, all iterations since then, while improving in general quality, have moved far far away from the design ethos associated with Shivan vessels. you might want to fork this, as it is nice looking in general.
