Mmm, that does sound negative... I do agree there's something wrong with the tentacles (supposed to be like a jellyfish's), as well as the general shape of the creature, but I can't put my finger on it, and I'm not sure what to do to improve it. It's supposed to draw water in through the mouth, and expel it through the rear, propelling it in a sort of jet-like way not entirely alien to a squid or jellyfish, but not quite like anything terrestrial, either... that I know of.
And yes, Reudh, I'll throw together a brighter image for you, using the same model. I'll put it in my old "box room" and do a render... and then I'll have to do another render because the box room absolutely kills bump mapping. A lot of the shapes and lines on its surface aren't supposed to be fixed, as it can change its colors like a cuttlefish... but... there's no way I could possibly animate it. I'd have to render a separate texture for every frame.
To be honest, the creature was designed with the plot in mind, which is why I mentioned them in the first place, a number of chapters back. The glowing makes it easy to see, the tentacles or whatever serve a purpose, as does the fact that they feed on discharged electricity. The coloration is nothing important - I just made it match up with a sentence I wrote in the "interlude" segment:
You stand in an underwater chamber, the ceiling at least fifty feet above... For years afterwards you'll struggle in vain to describe it, for the beauty is otherworldly: a cathedral of giants, complete with glass walls and steel beams, towers, buildings, embattlements rising up all around you, continuing far into the distance, the water outside as crystal-clear as if it's naught but a glass of fresh water. Alien creatures, shimmering in iridescent beauty, sail gently by outside.
I'm sensing a great deal of negativity here, though... which wasn't entirely unexpected.
