Not a lot of Vortex (mainly just good water FX), but one interesting quick one as the monster emerges to attack the main character. A kind of reverse Vortex, or a focus on one forming and then dissipating.
Water Vortex, very subtle tornado like structure, big whirlpool at the end. Nice, consistent, digitally inked (probably animated). Some of the effects appear to be on 3's perhaps? Just have a slightly more limited look than the characters, but not in a bad way.
