How does use imagery in The Epic of Gilgamesh?

Imagery:

The roaring of Humbaba was like that of a storm cyclone; his mouth was [full of] blasphemy,his breath [killing] like hot wind.
-- Gilgamesh (Tablet 4 paragraph 12)

There they stood, lofty arose the forest, and [astonished] they gazed at the height of the cedars and at the entrance of the cedar wood, where Humbaba was wont to walk with lofty steps.
-- Narrator (Tablet 5 paragraph Line 1)
