I like the idea to watch over a giant army preparing for war,
the idea is kind of epic but the realization far from it. All looks
far to neat, the trees and the camp itself. Regarding the
background i think all important is mentioned. Concerning the
camp i would suggest to spread the tents, set some fire pits,
maybe a place where they keep their food (animals...), maybe
a small arena.
And I think the hut should be a bit smaller from this perspective.
