You've nailed it on the head; Glamour will work in whatever way @Sashira pictures it.
If one looks at the various stories of the Fae, Glamour can go from low level illusions like Goblins in Monsters does all the way to full sensory effects - changing tastes, hearing, smell, etc.
That said, it might be possible for a Goblin to even be able to tweak their glamour. Your example of someone making themselves more beautiful might be in the realms of possibility.
Of course, given how most Goblins aren't concerned about appearance, someone spending time on that would probably be considered superficial by the rest of Goblin society.
