Actually, I love the idea of this film, and I’d love to see even an OpenGL rough-cut of some finished scenes.
To my way of thinking, there’s absolutely nothing the matter with a “very stylized” presentation. (After all, we watch cartoons all the time.) I could instantly accept the visual absurdity (“all too close to the truth,” etc. …) of a scene like the first one, with the perfect(-ly awful) lawns, the identical houses and mailboxes, and consider it as part of the story, as I eagerly await “what happens next” as a would-be meal heads off to the beach(!) in order to find his shell(!!).
And as for the next shot … the same. If that little snail-guy exudes charming-personality and stage presence, and the two purple (hey, why not …) snails are suitably oaf-ish … “I, the audience, am eating out of your hand.” (But, I promise, I am not eating snails.)
If you make the artistic decision that this should be a very stylized picture, with a healthy element of visual pure-absurdity, and are consistent with that premise, then: “I’ve got my popcorn ready. Just Tell Me a Story.™”
So … “is it finished yet?”
