Nice
The more organic look of the cables and the additionally antennae provide a nice counter point to the segemented armour plating, like the more obviously engineered looking parts encasing something - Are you planing to reinforce the contrast in the textures too?
BTW are we going to get some additional destroyable subobject for the Ravana, just like with the Leviathan? - It would help with getting the Ravana out of the "take out the LReds"-rutt that it sometimes comes in.
EDIT: I like how this model looks but I'm not sure about those 4 long thin claws/barbs coming out of those 2 nodules on the cables. They just seem like they're something for Shivan fighters emerging from the starboard fighterbay to crash into for no good reason. They're not part of any subsystem, are they?
The 3 $bay paths should take care of that, like in the original (for illustration, see attachment)
