My first web design - need critique

Hi everyone, I am principally a video cameraman, and graphic designer but am keen to venture to the world of the web, this is my first design. This design is for my mothers Holistic Therapy company. It is still just a basic layout, quite sparse. The content and photography are temporary as i will take bespoke pictures or the site.

I need some tips as to where i may be going right or wrong with this idea as i feel it is somewhat lacking!:cross-eye

Thankyou in advance for your help!

Simon
