That is Fantastic! I slaved away with PVA / Sand and a Stick to create all the bricks on My Deep.... had to paint them all idividually for a good effect... resin looks the way to go.
Particularly liked the open back for gaming into the Deep!
( I made the top of the mountain detachable on mine ... but moving the figures was a pain and you couldnt really see the battle roaring inside.)
I have just finished making some modular mountain pieces for the Rohirim to charge down for scenarion 16 and a full seige battle.
There is a pic of my Helms Deep too, as I am trying to relocate it!
Seems that the new rules will breath more life into large gaming board like this.
There are some pic of the Mountain boards on the last alliance web site if you want a peek.
