mossy rocks from Princess Mononoke

i'm trying to see if i can manage to replicate some scenery from princess mononoke. that movie has some of the best backgrounds and if i were to start getting more into scenery painting i think this movie would be a good place to start practicing. uhhh this scene right here is a shot from the movie when ashitaka first sees the little tree spirits. there was originally a tree spirit in this image but i did not include him, sorry little kodama
