Dug up some old photo's and will post some new ones soon. I've gone for so far in my army build a solid unit of Treekin initially 4 strong but will be fleshed out to 6 strong eventually. I started building them out of Sprue (yes plastic sprue) a while ago and here are some shots.
To go with the Athel Loren army you can't go past a Treemen so I've started work on that colossus as well...
A comparison of the Size of the Treekin against the Treeman.
More to come later.
