Lets remember these rules. They are on the mark. It usually takes a great deal of knowledge of both art history and concepts to understand the second rule but still I think the galleries and critics can more often than not use it to there advantage.Most people evaluate art based on these three things:
1. the esthetics - Does it look good? Did it take skill to make?
2. the concept - What does the piece say? How does the execution of the piece add to the meaning?
3. the monetary value - the higher a pieces financial value, the more people appreciate it.
Personally I appreciate actual skill. Kirby had oodles of it yet most critics bashed him. The same for Kinkade.
