If you showed a painting to 10 different people, you would probably get 10 different opinions on the work. All due to the different perspectives people chose to view things from.
If you asked those 10 people what could be done to make the painting better, you probably would get 10 different answers, all from varying perspectives.
What makes one thing better to one person makes it worse for another.
Show a partially completed painting to those 10 people and some would say, "Nice when it will be done", others might say, "It's crap and it will always be crap", while others muse, "When are we going to find out more about it?" Perspectives are interesting.
