Valium, once again!
Integrity is hella important. I think that is one of the biggest lessons I learned at the Art Institute del San Francisco.
For instance, I recently came across a painting of Mark Ryden's that I found quite upsetting. It was something I had already dreamt up, and he apparently beat me to the punch. His was exactly what I had envisioned. Am I going to do it now? No.
There is a difference between borrowing shapes, colors, and ideas and building on them, and then there is just straight stealing.
