Nothing exemplifies using mermaids and "The City of Canals" aka the gorgeous Venice in the same work than the stunning work of mizunomachi by *Harukim. A beautiful color palette with a detailed background and composition, a viewer can only wonder at the amazing experience it would be to see the city in a classical Venetian Gondola and seeing the playful, frolicking mermaids in their games and swims! Truly charismatic! (Also suggested by =reiashford)
