my sister's painting

There is a pleasure in painting which none but painters know.

When we look at the imporatnt of painting,There had been difficulties defining it, but as it was defined in general, it is the product of creative human activity in which materials are shaped or selected to convey an idea, emotion, or visually interesting form.

Make judgments, but get specific..that is one of the rules of painting. You can’t say something isn’t an art just because you want to say so; you have to give good reasons. Originality, individual expression, something to contemplate rather than use..these are some of the qualities that are commonly associated with art.
