I really appreciate all your answers and suggestions. I originally posted my question here on November 6, 2023. Since then, I've implemented almost everything you advised and even met with my success manager twice for further guidance. I've put their suggestions into practice, but unfortunately, I haven't received any messages from new buyers or new orders in nearly three months. Regarding the quality of my work, I welcome you to check my profile for my recent projects and reviews. These buyers are all repeat clients, which I hope speaks to my dedication and skills.
If you have any further suggestions, I'd be incredibly grateful.
