Not historically accurate as I felt the sort of tree-bark texture was much more visually interesting than a grass structure.
Waw, very nice!
Great job with the shape and form from the top-down perspective.
I like this a lot. I think it could be improved by adding shadows to the cloths to give it a stronger form, and more contrast wouldn't hurt.
would use a little thicker outline at the lower parts, transitioning to the thin upper one :p
aswell as increasing the contrast on the lowerlevel parts to increase depth
the entrance is supergreat aswell as the gradient shadow
i loved doing wood textures
