Hi, here is my interpetation of ANZAC cove - quite simple, but it may do.

I'm working on some cliffs now, maybe the third or forth try will bring some useable results (a first try you can see in the right corner of the first picture) ^^

The pins may not be really necessary, but I tend to mess things up when I'm in 'combat-mode'... But I should  disguise them a bit more.

Stick some scrub / scatter flock on them, that should do the trick.
