Back in the early 80's, while in the RAF, I used to do a lot of Science Fiction paintings and black and white "illos" for SF fan magazines. I did a bit of work for "Quartz" and the BSFG Newsletter, I even did a cover for "Vector" ( Issue 103, August 1981). I count myself very lucky to have known Ann O'Neill, one of the early pioneers of media SF fanzines in the UK, and a lot of my artwork was featured in her early "Standard by Seven" series. I sold quite a few paintings in the Art shows at SF conventions.

In the early 90's I did a lot of computer art - mostly using Dpaint on the Amiga. Extremely basic stuff by todays standards. It was used in the "Total Concepts" titles I developed from Chris Hill's brilliant originals on the Amiga (Chris - Where are you now?) for use on DOS based PCs. You can see some of the results elsewhere on this website in the sections on the Tornado, Harrier, Jaguar, Hawk, Spitfire and Messerschmitt Bf109. One of the other titles was "Dinosaurs"...
In every company I've ever workled for I've usually ended up doing cartoons for newsletters and promotional stuff.
