I mostly use oils these days. There's something leisurely, even sensuous about oil paint that makes it a delight to work with. Want to break off half-way through laying in a huge, sprawling sky, and come back to it next morning? Then oils are your media. Want to have a nervous break-down, trying to fill a four by four inch square without leaving visible brush marks? Then choose acrylics. On the other hand, if you want to get the work in the post the next day - ah, well, it's acrylics again, I'm afraid.
The majority of works on this page were done for various magazines, it hardly matters which as the relevant issues are all long gone. The aviation pictures, however, are an entirely different matter . . .
