Sometimes it does not take too much to create a really nice piece of caricature art. No fancy props, complex background or high tech input.
Here is a nice simple caricature by artist Zalo. It shows that from a photo that is fairly ordinary (especially is others are in it, as was the case in this sample before it was cropped) this can be used as the basis for something special.
A caricature like this can be poster printed, framed, printed onto a T-shirt or coffee mug, used as a social website avatar, blog etc.
