It is a tuff work to express emotion through art but an expert artist makes it possible. I am running on same platform since 2003 and have a network of famous artist. Last time I meat with Ashish Mondal, A famous artist having expertise in emotional art painting. I asked him “how to give expression to the art”.
Giving emotion to a art painting is an act and it is gift of god which comes out through my hand but one thing which I want to share that you only can do such work if you feel it, imagine it or map it.
