I still need to add weapons platforms. I adjusted the model last night after rendering, with 3 ballista mounts over the neck and a catapult in the rear top shell. I'll make the adjustments and re-render, but this is the job I've done so for. Now there is a canon Sea Turtle Spelljammer ship that is capable of being a submersible. Well I did my non-canon version based on an Alligator Snapping Turtle shell and head - as it is more scary. Added marine turtle flippers and rendered it.
