Both of the maps have a couple of unique touches. For example, both have images of their inhabitants on it. The Lost Isles map has a particularly ugly female Goblin in a bikini while Gilneas features a human in Victorian garb. The latter also has a couple of shredded bits as if a Worgen adventurer had used his or her claws when trying to read the map. The Goblin map features a scattering of indented gold coins at the corners, as if to hold it open. Both are awesome little touches that add that special bit of pizazz to the new zones.
But the maps do give us a proper glance at what we can expect from the two zones. Gilneas is dominated by Greymane Manor and the town of Duskhaven. Looking at it, I was expecting something a bit larger, but then you remember it is a starter zone. The Lost Isles is smaller still with an Alliance encampment to the North and an Orc settlement to the south, which explains their presence in the trailer.
We should note that the Gilneas map is only part of the Worgen starting zone. The city and the Greymane wall are due East of what's presented.
