oh somehow i got the idea that you could pair normal and displacement together (when i did the normal map was warped like the colour map would be)
but anyway, this is all just displacement mapping i shoved onto the wing rather than the usual normal mapping i would do

the spiky things are detachable, they are sword-like weapons that float unattached to the ship. They just dock in the wing when not doing anything.

basically, since this race is telepathic they should have some mind control over stuff on their ship

also, you may not notice but the wings aren't actually attached to the main body :p
i think to keep the whole telepathy theme they won't be attached.

the barrel-like shapes on the main body also split up to charge up the giant particle-energy cannon in the center... being space energy weapons are greater than explosive weapons
