That picture is awesome! It looks like a creature, a wooden sea horse :<)
The process you shared of minting a piece look exactly like NFT showroom where I have been minting, buying and selling art in the last couple of months. The unlockable file can be seen as a bonus that you give to the person who buys your art. You can add a different kind of file / different media there. For one of my pieces on NFT showroom, I added an audio file where I read a little story I wrote, connected to the art work.
Have a nice day and congratulations on reaching the impressive number of 1 million views on pexels.
