The snail dragon is one of the creatures I designed for 'Project Loui'. Conceptually, its origins lie in 'Lou Carcolh', a mythical beast from French folklore. This design is loosely inspired by the Pokémon franchise's approach to 'Goodra' and its rough head shape (horns especially) are a tiny nod to Monster Hunter's 'Gore Magala'.
Project Loui is going to be a Visual Novel, which began as a semester project and is still being developed by two of my (former) fellow students and I.
