That second concept gives me the feel of the Shivans from Freespace 2. I've always found the two races somewhat similar, in that they both have highly advanced weaponry and mysteriously appear from nowhere with no real reason why.
How wide would the spines be on the second concept? Are we just talking like the fins on the bomber, or wider, 'petal' styles?
A million dollars isn't cool. You know what is cool? A basilisk.
