You need to create more to determine your signature aesthetic, and there aren't many shortcuts along the way.
For me, I followed the work of people whose images I loved. Most of these photographers used Contax 645 cameras with Fuji 400H film. But I learned more than the equipment they were using, I studied how they used light, what the colors looked like, how they posed their subjects, the story they were telling, etc.
This helped direct me into the style that I wanted to produce... it was then just a matter of practice to create more of it!
