As an approved photographer on stock libraries, you can possibly get access to client briefs where you can submit your work direct to the client, meaning they’ll consider you for the project and see your profile. Otherwise there’s usually a marketplace type system for you to upload your images and have them added to collections based on themes, destinations and seasons.
Despite that previous statement, I do believe that the travel photography community is stronger than it has ever been. Yes, traditional forms of income-generation are dying, but the evolving world has opened up a thousand different doors for those willing to take the risks to make it in the industry. And, yes, there is a lot of competition out there in the travel photography world, but the community is strong and the amount of camaraderie rather than jealousy in the business absolutely floors me nearly every day.
Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
