I tried to portray Cthulhu not as a creature, but as the vessel of some awesome cosmic entity.
I tried to capture the Dunsanian mystic atmosphere of "Dreamquest of Unknown Kadath" mixed with the objective view of "At The Mountains of Madness."
" ...a gigantic thing "miles high" which walked or lumbered about."
It can´t be merely a creature of flesh and bone, but Something alien that extends to more than one reality, and which draws its power from some distant cosmic source.
Like what a 2-dimensional creature living in a 2-dimensional world would see if we sticked our 3-dimensional finger into their world.
" ...the mountainous monstrosity flopped down the slimy stones and hesitated, floundering at the edge of the water."
" ...great Cthulhu slid greasily into the water and began to pursue with vast wave-raising strokes of cosmic potency."
It seems like a gigantic mass gliding about, like an overgrown Shoggoth.
I prefer this cosmic horror better than the hairless King Kong with the octupus head.
