This is awesome! For any painter, freelance or any kind of artist, this will get big! I need something like this for selling Shirts, photos or accessories...

Pros:

• You can earn some extra on the side
• It is an investment
• Refering can earn you some extra
• Virtual art / paintings are being collected on one page

Cons:

• Could be built on steemit :D instead of using metamask (not a fan of it)
