This is my 2nd piece for Games Workshop, featured in Battletome: Everchosen. Really happy that it became art prints and displayed for marketing on their web too :D

Above is an older version, initially I had the dryad's head chopped off, flying in mid-air. The Treeman was also on the left. Although I see the intention of change- riding towards an obstacle, I still quite like the version above.

rough sketches below.
