Maybe he just wanted to sell his own craft as NFT images, but he probably didn't understand how to sell and set a price accordingly. sale.
Especially with the price of 10 ETH I think it is very expensive.
It is better if the price is corrected again so that it is really considered to be able to sell.
From what I see, the pricing in the NFT is based on whether or not it is complicated when the image is made and even then the owner of the image can adjust it according to his wishes so that many images in the NFT are not sold because the price is not reasonable.
