Good point about the Eye. I'll give it a blueish hue.
The way the Guardians are currently, they basically are starships, with a different name, but 90% the same behaviour. Can't deny that my subconscious probably wants them to follow the common setup; mobile ships mostly symmetrical, statics guard posts asymmetrical, to have a pattern, and more easily identifiable icons.
In the end, it's up to Chris to make the decision whether to include this or not. Aside from the red cockpit, I don't think I'm going to change it for now. And since no one objected the cockpit, I think I'll focus on other stuff.
