One look at the portfolio and the customer knows this is not someone who took pictures with the buyer in mind.
You have to think of the buyer first, make a mood board of what you want to shoot, then research what is already available and at what quality level, then go out and shoot something much better or with a new idea.
The more effort you put into planning your shots, the more money you make.
stock is not a photohobby plattform chasing likes and hearts, it is a business.
Your portfolio has bad descriptions and keywords, it is also not organized by themes.
If you put no effort into it, why should anyone give you money?
