With Bob's and Edel's recent posts about self-editing one's work, I remembered wondering the same thing about a promo piece that I did as a contribution to an artists' group I am a member of, "BIG" (Boston Illustration Group).
My piece is BIG Science and I showed the four elements: earth, air, water, and fire. Was it too much for ADs? I guess, as it did not bring in any work but I am glad I did it. I had fun.
