Very nice, Wonderfully put together. Only criticism of it is that there isn't any of us Aussies in it.
I will say that this is really neat. I also didn't realize it was VC until it zoomed in on them. This is really neat!
Hey devil dog...yeah the Aussies didn't always either...just a 'pet' love for working dogs, military especially....did you do this sort of work?
Nice job. Reminds me of this book. http://www.amazon.com/The-Tunnels-Chi-Underground-Battlefields/dp/0891418695 The Tunnels of Cu Chi: A Harrowing Account of America's Tunnel Rats in the Underground Battlefields of Vietnam by Tom Mangold (Author)
I like it....what unit were you with? I was with barracks 83--86 [82 boot], and 3-6 86-90...my wife's uncle died with B 1-9, from what I've read, they [ B ] were wiped out July 67 Operation Buffalo, ..B was point, I think...one of the worst ambushes of the war....if I remember correctly, haven't read it since the 90s...
Quick scan on google images and you find a few more VC tunnel rats diorama's. If it is not too late, maybe you should make the entrance smaller...much smaller. To make it more realistic and more sinister... (to make the area underground smaller is perhaps too much work) example: http://cs.finescale.com/fsm/modeling_subjects/f/19/t/148506.aspx real: https://cherrieswriter.wordpress.com/2012/08/04/the-vietnam-war-tunnel-rats-guest-blog/
