CryptoArt and how to sell it on Blockchain.

Hi All;
I am new here and as my first post I would like to show off some of my cryptoart and share how I managed to sell it on blockchain.
Firstly I created some digital art which i have shared below.
Then I signed up with KnownOrigin and OpenSea who assigns a blockchain tag to the art and sell it for crypto currency that goes straight into your wallets.
The only hurdle is working out the "gas fees" and ensuring you get sufficent returns to cover the ETH transactional fees.
Once you get an understanding of the fees you could become a successful cryptoartist very easily.
You can look at some more of my work on these links...
