I have no idea how many hours went in to this project. A lot. 3 to 4 months at my usual pace of work. I had to kit bash from at least 4 separate Warhammer boxes to make up the few models that ended up in the scene. The tree itself started as a downloaded stl file of a dead tree which I adjusted before printing. A lot of extra branches (of actual stuff from my garden) then added by hand. The foliage then added slowly by hand also.
