I've never cared much about pop art, but I've always loved the daddy of this artistic movement, Andy Warhol. His concepts flew in the face of everything that was considered true art; it was technically repetitive and very commercially influenced. He once said "I wanna be a machine". Erase the ego and emotions from your artwork... Just create!
What others say about you is none of your business. Stop worrying about comments, critiques and prejudice. Just get busy with your artwork... The rest will sort itself out.
