Not sure if I mentioned this before but I started using a vector graphics program called Inkscape. It is absolutely fantastic as well as powerful. You can make anything from art so realistic that it looks like a photo, to clipart and cartoons, not to mention things like logos and illustrations.
This sad faced beagle is my latest made in Inkscape, it’s the sixth in a series of dog pictures I been making. The rest can be seen at www.pets.styleartc.com/dog-art.html
