ooooh... spectacular sound design O_O so many big, deep swells and a lot of cool effects that i think strongly convey the deep sea locale. i'm super impressed with the soundscape here, and i can only imagine if this is what you're bringing to the table you will excel in film scoring too. this is massively creepy, unique, and delicately crafted. the light presence of solo cello really sells it too, giving us something slightly mournful and uneasy to latch onto that's clearly acoustic amidst all the processing and cinematic sound.
geez... this is just so good, i'm really inspired by this one.
