It's not a black and white issue. I was just pointing out some concerns people have with NFTs. I am not against them if they help artists. A lot of them will be for purely digital art. There are ongoing debates about the energy usage of blockchains. Elon Musk is getting involved, but the miners are going to use whatever optimises their profits. Hive is not so energy intensive as it does not use proof of work.
You can sell digital artworks without using NFTs, but they confer more exclusive ownership.
As I understand it what is on the blockchain is a sort of ownership certificate rather than the artwork itself as storing that much data there is not practical.
I get the concepts, but it is a much-hyped area right now. You seem to be a rare case in working with traditional materials to produce your work, but then animation is generally going to need digital, unless you resort to film.
I have issued my own NFT in the form of a song that can be bought in the Rising Star game. It is a limited edition and I can set my own price. I do not expect to make much from it though. My music is also on sale on Bandcamp, but I let people pay what they want. They get standard audio files, so there is nothing to stop them copying. People will pay anyway to support the artist with no need for NFTs, but they offer another option. I think it's great if you and others can earn from your work in this way.
