Several basic information are missing... it is an auction ("price start") ?
have you already produced other works of art in the real world? are you also selling on the NFT market? Mintage? In which blockchain is running (polygon/ETH/Xdai?)
Last but not least, how did you arrive at the valuation of 300 USD? Actually this image has just 2 visits (3 with mine)...
No it is not an auction.
I sell my artworks in local galleries and am taking those online now. NFT's seem to be a great platform supporting such artworks so have started with my crazy artwork collection.
I am not selling those on NFT marketplace as of now. I am selling those to direct customers interested in my collection.
I am running those on polygon.
$300 is not the exact valuation. I am hoping for the interested parties to quote their perspective of valuation.
