Here we have a simple screenshot of a Night Elf base.

Going throught the buildings first, we can see the building on the far left is a completely unknown building, not even the name of this thing is known or even what it does. Just up and right is what I suspect to be the place where Hippogryph's are trained, you cannot actaully see it in this shot, but the building has a small nest poking out of it and some eggs in it, although i cannot say for because Blizzard have told us nothing about it. Just to the right of that is the Altar of Elders, in which you will ressurect your fallen heroes. The huge building further to the right is the Tree of Life which serves as the Town Hall type of building for the Night Elves, it has used its entangle ability on the Gold Mine in which it sucks the Gold directly out of. Down the bottom left is yet another completely unknown building.

With regards to the units, top left we have a Dryad, middle left is a Druid of the Claw, just next to him is another Dryad. Underneath the Altar of Elders is a Sentinel and an Archer. Flying high in the middle of the screen is Priestess of the Moon Hero, and down bottom right is yet another Dryad.

You may also notice the blue sparkling lights across the screen, these are the Night Elf Wisps and act similar to a Peon unit - they morph into the Ancients (Night Elf Buildings) and they can also attach themself to the Tree of Life to make it mine faster. -Chib
