You need to know that not all NFT are sellables and you cannot expect people to buy your art if you announce it as NFT since you need to be good on hyping up on your creation. And also you need a good reputation so that many people will get attracted on what you are offering to them so better work out on your portfolio first and create demands thru your supporter so maybe for now its better for you to build a community first before planning to rush all things here.
