Research on Artist job
What I'm going to be writing about is; the amount of money the artist class make a year, the education level you have to have to make a good use of being an artist, and the time you have to put in your art to make it well known and good looking.
The amount you make as an artist is almost a variable, it depends on the amount of education, the look of your art, how willing you are to change on the desires of the buying person, how much you spend to make money, how much the person is willing to pay, how good you are, how well known you are (as you see you can be a VERY bad artist and if your art is well known, you make more money than a person who is not well known and is better than you) As I said, it is practically a variable it depends on so many things, real art is almost dead. there are also people who will pay 10,000 for some nonsense paint thrown on canvas, saying, "I love the abstract look of it." But artist usually make about 40000 - 60000 based on experience.
The Education level is not really a part of it, unless of course you want a faster growing popularity level and the amount of money you get for one piece of art. Like if you have a college degree your art will be way more expensive than a person who just out of high school started there art. If you get a college degree you will be way more popular than a person without one as well, like picture, if you were talking to a person about your art and you say, "yeah, i went to college for four years, just for your painting sitting in front of me." the buyer will pay more.
Time to put into it
The amount of time you put into a piece of art is entirely up to you. Although spending too much time on one piece will set the buyer thinking your not as good as the one who says "one week." But if you spend a reasonable amount of time on it and it looks amazing, the buyer will pay more for the next piece of art, and recommend you to others. For the ones who have art set and ready the buyer will look at them and think, 'How much effort? How much time? Ready to go? He/She might or might not take it (Its all depending on the buyer)
