Remember to study people in the profession. If your work doesn't not match the quality and refinement of the professional work then why are you doing it that way? Ask yourself what ages did Da Vinci and Michelangelo start working professionally? Then ask... What is your excuse? The execution of work is what separates and amateur from professional.
What is the format used for work in that matter? You need to also take into consideration who is your cliental. What problem are you solving with you work? How is your work the solution?
