[Narratio]

Like the concepts. Ignore the peons though, keep the eyes, consider adding tendrils / cillia / thin wavy stuff. These are organic, you need some organic antennae. Get rid of the hard and techno looking fins, try something more fish or bird like... Dragonish whip tale perhaps?

(I use an organic tech race and I wanna' decent shipset, thus the comments. If I'm gonna' steal something, I've got to like it)
