Thankyou for your creativity ness. Your art is excellent and looking fantastic. I think need attractive description about it. If you brief It's importance then it will be more acceptable for invertors. And i also think it’s price which you wanted 0.77 ETH it is too high. I think you have to re consider about it’s price.

I thik your NFT is good and also attractive if you describe it properly and It's price you consider, there will be huge possibility to sold it. And you can advertise it on several social media. It will be helpful to sell Your NFT i think.
