Welcome to Hive and thanks for sharing your art in the community here!

All you have to do to be accepted in the NFT Showroom is private message from one of your social media accounts just to verify you are you. They don't look at your portfolio or art. You can join the discord for NFT Showroom here: https://discord.gg/k5t3fUcE2T

There is a FAQ sections and the folks that would verify you are there as well. It's quick and easy and everyone there is nice. Hope you consider getting onboard. =)
