Personal branding ideas?

The last couple of weeks I have been looking at ideas for my own personal branding.

I am just using my own name 'Sam Burgess Illustration' or 'Sam Burgess Illustration and Crochet' to keep things simple and make it obvious what the brand is about.

But i'm not totally sure about these..it's something I need to look into more I think.
