My first professional graphic design experience lies in the largely client-driven designs I have produced (print and web) for the promotion of Circa (UK) Ltd, since 2003. More recently, I have taken my own direction in the web page headers and buttons I have created in collaboration with Global Websuites.
I usually produce all my graphics from scratch, hand drawing and digitally manipulating many of the images you see below. Sometimes I start in photoshop, and incorporate photographic material.

(Circa's 3D globe was created by Peter Moran.)
