Hi, it’s good to see newcomers to the world of NFT. Building your own NFT collection is a fun and creative endeavor. The first step I would suggest you check out resources where you can get detailed instructions. One such resource is https://romtos.com/learn-more-about-the-product-owner/how-do-i-create-an-nft-collection , I used it to build my own nft. It’s important to remember that design plays a huge role in drawing attention to your collection. Being creative and unique is always important. I recommend researching the market and analyzing successful NFT collections for inspiration.
