Likely this will become my Treeman Ancient for 2250 and I'll do another less converted one for a normal treeman sometime. Its the stock
GW treeman model with dryad bits added and the arms moved around some. Base is from MicroArt studio and has about 1/2" worth of greenstuff sculpting on each leg to make it blend into the model itself. The face is converted using the head piece from a dryad to create the cthulhu-esque look. Painted the same as my other trees.
