Either way you end up in the same place — your contract on-chain, your art in storage, and a mint page people can buy from.
Start from a blank canvas. Draw each piece — backgrounds, bodies, eyes, hats — set the odds, and Finch Crew shuffles them into a whole collection.
Bring your finished images and their metadata — one json per image, named to match. Finch Crew doesn't write the json; it checks every pair, stores both and deploys the contract.
