Hmmmmm, the artist's integrity, huh...it seems to me the integrity is in the art, not particularly where it's displayed. If it's a choice between Starbucks and the bedroom closet or living room wall, I'm gonna have to go with Starbucks.
Whether it's considered art or 'just decorative art' seems to me irrelevant and out of the artist's control really...get the word out, get on paper, get some exposure and then fuck it, see what happens...
Besides it's abstract painting...hyped-up, crazy-eyed, caffeine-snorting Starbucks customers may the only ones able to comprehend the essence ;)
Good luck Reasonknot and congratulations.
