When you analyze an artwork and you need to give your own and personal opinion on it, you go through a series of thoughts and evaluations before formulating your final decision of whether you like the piece and think it is successful, or not.
Evaluation is one of the steps in traditional Feldman model of art criticism where you have an opportunity to discuss your development, opinions and final work. It helps others understand what you were trying achieve and enables you ascertain if your artwork is successful or not.
