Making artworks like paintings, coloring arts, Canvas master peace, cartoons, and digital or computer made artworks are really interesting and in demand to the public especially in our modern days we accept and purchase digital and computer made arts and lettering even more.
Fine arts is more on painting so we can't include other artworks for this discussion, I would be the best to choice artworks from the school of fine arts, and it's really advancing and the creation of every painting are really detailed and amazing.

All it took was a little over 8 minutes to set the record price for a piece of art sold at auction. On May 4, Christie's sold Pablo Picasso's Nude, Green Leaves and Bust, a painting created in the span of a single day in 1932, for $106.5 million dollars. The painting, which is of Picasso's lover Marie-Therese Walter, was previously owned by a California philanthropist. The price beats the previous record for a piece of art, set this past February, of $104.3 million, for Giacometti's sculpture "Walking Man I." This is not nearly the first time a Picasso has sold for a record price, however. In 2004, the painting Boy with a Pipe (The Young Apprentice), sold for a then-astounding $104.1 million.
So, Amazing right? if you the choice to be a good painter you could do this, however, the population of good painters in the world is rising and you are not just the only person who can really paint good arts but they are almost a million of people can do, so you must do the-the best painting right now! and sell to the public.
