Great ideas there bud, I like your NFT cards very much. I've just launched some NFTs of my own on Hive at nftshowroom.com where there are no gas fees. Opensea and rarible.com are too pricey on ETH gas, which is a turn off, though I have accounts there. Unfortunately on Hive there may not be much reach, with only a few people using it.
Your NFT cards will look fine, especially if they are all in a similar layout and pattern, with central image and name on top and details in writing around the pic, so it looks like a real card. I'm impressed.
