You're really talented zomberry.
Well, it's an awesome hobby. Art as a profession is tough. Many many people do it successfully, but it's not high on the list from a stability and income perspective in general. I really respect artists who have chosen to devote themselves to it as a career. I consider it a self sacrificial step in many ways and instances. You have to be really passionate and brave. This is mostly for the fine arts. There's a lot of commercial opportunities for artists, but most fine artists don't like designing mud splashes on the new Jeep Wrangler in whatever program they are using now for Chrysler's next Superbowl commercial.
If my family is rich enough I would devote my life to art. As of right now I am way too poor to support myself through art. Also I'm not that into the art trend in USA. If I were to become an artist, I would probably move to Europe permanently. The whole point of being an artist is to be true to yourself and self-expression. If I were to do commercials for money, then I might as well do something else that makes money, like engineering or banking.
