Go make your own art and sell it as NFT scammer. You actually have the mind to go to another artists page and get mad at them for not allowing you to make NFTs with art you have not contributed to. Take yourself elsewhere. You are on this site to get over on people and you will get called out. To use any art as NFT you will need to ask the artist directly and is in no way different than selling the assets by themselves which almost NO ARTIST will allow you to do for free.
