With all the cool galactic stuff out, it'd be nice if there were a few more eyes and lips that had a galactic and aurora borealis feel to them :)

I think a good deal of the galactic items out are CWs so personally I wouldn't mind seeing a little variety in onsite items with that kind of theme anyway.
In the meantime, depending on the "shade" of galactic you're using, works pretty well (and it's possible to hide the eyebrows if needed, if you're only using it for the eyeshadow). Though that just retired too, so :P
My only issue with this is that CW creators seem to have a different sense of what "galactic" means that doesn't match up with official items. So like if you're looking for something with pinks and purples that matches your current HA, that's not really "galactic". That's just a terminology thing though; I'm not at all opposed to this idea otherwise. :P
/minor pet peeve

There's a pretty big difference between Galactic (the special color for our pets) and galaxy (the rainbow-y outer space coloring that I think finally died as a real life trend this summer)
If you're specifically talking about the subeta color Galactic I'm not sure how it would work for lip items, but I could see some pretty navy with gold colored eye makeup. If you mean galaxy coloring, we do have that lip gloss from Melody's Cottage from 2 years ago. Eye and face make up in slightly more rich colors would be cool.
I would love to see some eye makeup that would match the Nebula skin and cover the skin's base eyes. Only because the eyes are so low and don't work with any makeups (which sucks because I LOVE those eyes but they are so hard to work with)!
That said, I also would love any galactic/nebula makeups. :3 Lovely eye shadows, two-tone lipsticks, or even eyes that are multi-colored in galactic color schemes. :)
