Mmm what to do??

I already have a photography business which is named 'kimberley jayne' but as I am also going into graphic design do i:

a. design another logo called 'kimberley jayne' of which would work over both graphics and photography.

or

b. do I create my own logo for my graphics and keep the same logo i have now for my photography and keep the two separate?

I quite like this little number:

without the lines??

Think ill stick to using the I'm kim thing for my graphics and use this kimberley jayne for my photography.
