One thing you can’t help learning about photography is how your work compares to others. Just as if someone placed a file on your desk with something wrong with it, photographic source material can have the same problems.
Get critiques and feedback online and get the skinny on what kind of photography “survey says” you are best at. Concentrate on those market and promotion sources for revenue. Bring on the marketing plan and schedule long and short term goals. A short term goal might be one style and beauty image sold, and a long term goals might be a monetary figure for overall sales total in cash.
