Alright, at last someone heeds to my message of ‘get permission first, post to site later’ (please tell me you haven’t sent it off yet).
So the idea is pretty interesting as well as the design though there are a few things that bother me that we may need to look over before we can go any further with this figure:
1: remaking the teeth, head, talons and tail end.
2: lore to do with young.
So first on the design. To fix the teeth, a good idea would be to copy and paste a Node Spawn Broodling’s head on instead of the current and then mess around with the teeth and chitin (just don’t turn it into a mess of spikes and shapes or it’ll look bad). The talons look a littleweak and if they were made right could become pretty deadly, though i have a better idea. Instead, give it little ‘jets’ full of compressed gas, when released the Node Spawn would suddenly gain a boost of speed which could be used to leap out the water, Full on rugby tackle a passerby and drag them into thebody of water which they reside in. And finally the tail which you said was instead a sort of natural trident. As cool as it may sound, it would be a little faulty in the way that it’s main mode of transport (the tail) would not be able to get it anywhere quickly enough. Instead, make this a tail and maybe put a long, scythe like chitinous blade justting out of it’s belly or sides so that is could kill someone by simply passing by.
Next up is the lore. For its kids, the lore you stated is unlikely as young only stay young for about a day before reaching full size, this whole time they spend in a hive being protected by Hatchers. The name too i feel is a bit off as they aren’t truly that massive, that’d go to the Destroyers, Behemoths and of course Charxek Thar. Instead, maybe something like a ‘Siren’, you could even give it the ability to mimic speech which would fit the name to a tee.
Overall I’d currently give this a 6/10, good enough to earn my trust but still not enough to get into the movie. Consider my points and i may give you a higher rating.
