Firstly, it is important to set up a domain name and a website. Having a website, as opposed to marketing yourself by means of a Facebook page alone, presents a far more professional image and brand and, furthermore, provides a means for potential clients to “connect” with you. It also serves to showcase your work in a professional manner offering them the opportunity to view your portfolio in an integrative way whilst, at the same time, being easy to navigate. In addition, it assists you in respect of forwarding direct links to clients requesting a specific field of work, for example, those interested in your commercial work only.
I do believe you eventually develop a unique style over time; however, this is also due to self-evolvement in addition to working towards improving your style with every shoot. I shoot, learn from my mistakes and then try better myself the next time. As soon as you become complacent, your work will never advance beyond its current state.
