The longer you look at a painting you start to notice different things. For example you see a painting of a mountain you would think "wow, really pretty" You would also think it was for relaxing but you notice something that changes your mind about that painting. To some up what I'm saying the longer you look at a painting your opinion may change.
Yes, i think the longer you look at the piece of art your opinion can change. The longer you look at a piece of art you start to notice things you didn't see before. Also, the longer you look at a piece of art you might start having different thoughts about it.
