I've seen accross Twitter some influencers with millions of followers that voluntarily offer free sponsored tweets to people like her especially crypto influencers who are not just there for advert purposes; they trade or write. These people can listen to her and help publicize the arts she has got.
If that is true, then please share some links to such people if you absolutely sure they would like to help out and ask for no money in return. OP could then contact them if she wants to.
However, she needs a twitter page to share the art too, and use hashtags to draw people's attention.
She has a Twitter page, but for some reason she didn't include the link to it in the OP. You can find it in her second post in this topic though.
This is her Twitter profile:
https://twitter.com/5KsanaI think it's the OP's duty to go look for what she needs, I'm here to share Ideas with her and there's nothing deceitful or cunning about the decision I shared, I spend so much time on twitter, I've found more than 3 influencers that look 90% positive for what OP needs,
https://twitter.com/BitcoinDesigns they sell physical designs of bitcoin; auctions. Op just need to invest more time and seek for help.
https://twitter.com/btcArtGallery they repost bitcoin arts for users on twitter and lots more. Everything is not being paid, the problem is that people look for fast reactions that's why they can't settle down to wait for the free influencers to get to them. Like I said, it's difficult to get their attention, definitely Op would find one or two that would repost her work. Through the friends or followers of the two accounts I just shared, she can start her journey on twitter, and I promise her they'll be positive impact if she takes it serious. I'm not meant to go look for links for her.
Thanks for Support
N/B: OP Always open up to them about the situation you have, they're humans and could get emotional too, lastly don't take their help for granted. People already complained about how deceitful your auction ended in the forum, if you continue that way people would regret offering help to you. Goodluck.
