Is it halal to work at this job?

Assalam alikoum My question is related to a job I was working on through the internet before, where I was earning money thats in crypto payment method, so basically I was in the niche of NFTs, I dont really know if you know what NFTs mean but if you search it, you will find some information about it. I was working for marketing agencies where they provide marketing services for NFT projects, and I would bring clients to these agencies to earn a commission. Now, these NFT projects, some have artworks, some have 3D designs, etc, and when I researched, I saw that if NFTs have artworks or designs of humans, then they are haram. My question is: Is the money I earned through getting clients halal or haram even though I wasn't directly selling artworks or spirits or anything, and can I still do this kind of job in the future? I'm sorry for the long question, but I need a detailed answer on this. And jazakum allah khayran
