I just drew and minted "Crypto Cliff Rider," my latest on-chain vector art through CryptoSketches, which I also used a lot to draw and mint on in 2018. Everything still works! Bravo for being light-years ahead of most everyone as an enduring platform, marketplace, and on-chain #RareDigitalArt pioneer.
Go to any #NFT there (such as this one at https://www.cryptosketches.com/sketch/81 ) and the site regenerates the vectors in the order in which they were drawn. Moreover, the vector code is directly stored on the Ethereum blockchain and not dependent on the originating platform for future-proof viewing! But of course I hope CryptoSketches continues its impressive track record of endurance and art-historical innovation significance.
