When it comes to expressing oneself, not everyone can get their deep feelings and emotions across in words. But when it comes to art, this is where your freedom lies. Be it a detailed painting of buildings or scenery or even an abstract splash of various colours on a canvas, it all means something to the artist. From the picture you paint to the colours you use; you are sure to convey your inner thoughts and feelings to a viewer who truly understands art.
When it comes to psychology, art is used as a tool for therapy. No one can stop you from expressing yourself with art, therefore, this is an important gateway to mental release. Plainly said, art is freedom!
