Do you think your #NFT is has some value, rare or other think?
I see the image and IMO since you are using a character for a flappy bird it self there should have some doubt on your #NFT as well from the copyright issue who is the original owner of that mascot. Take a good side, even you can't sell the #NFT but you can learn how to deploy and minted your own NFT.
I drew my characters myself, inspired by characters from flappy bird
