I think the idea is brilliant coming up with a creative service for steemians and a reward system that can self sustain the community members and creators and increase visibility for steemians.
this project has potential to evolve a lot, more over because the project is linked to CCommons.art and to GlobalSchool projects, so the covers can vary in different visual art mediums, apart from photography, depending on @globalschool 's student's interests and @ccommons.art invited collaborators
my first suggestion would be to let the artist explain a bit his/hers choices for the creation of the cover- what about the steemian(client) has inspired the final look of the cover and also add a donation qr code at the end of the presentation post :)
