In this class you'll be painting a beautiful bold King Penguin.

In this lesson you will learn to 

simplify the subject - you don't need to paint everything for a painting to be succesful.

achieve good tonal contrast - your darks need to be dark enough to release the light.

produce soft, subtle shadows using wet in wet watercolour.

The class is broken down into simple easy to follow sections so that you can pace yourself and enjoy the process. Although I've listed it as an intermediate class, even without any prior experience I think anyone could give it a go.
