I am a digital artist

I was never artistic at school when it came to using a paintbrush. However, when I got my first computer in the late 90s it came with a digital art package. My children encouraged me to give it a go, at first I was reluctant, but soon got the hang of it, three months later I was having and exhibition of my work, which is mainly abstract. People seem to like it and have been willing to pay for it. As one can send it by e-mail, it people all round the world, including some well known celebs have it. Although it is encouraging that people like it enough to buy it, I much prefer to create a picture for free just to make someone happy.
