Hi, Maria. Before you acquire a “better” camera, push the limits of the current equipment you own. Learn what works and what does not. Then you will know why and what you need in your next camera.
But, good photography isn’t about the equipment; it’s about emotion and story. From reading your posts, it seems that you are an emotive person. You can bring that emotion to your photography.
When you are ready to buy new gear, read these articles first.
