When you start working with a brand, get to know it first. Find out what the company needs and why they have chosen you. Strive to be in constant correspondence with the brand or with the intermediary agency in order to make sure what the task is and how you can perform it as well as possible. Create a quality photo, write a nice description by yourself, try, give them more than what they asked for. Impress them and show them that it is good they have chosen you, and that you are not just another influencer.
