Not too familiar with watercolouring but I have a portable watercolour kit which is a lot more convenient to carry around than a big portfolio case with newsprint.
These life drawings are from an evening life drawing class at the Toronto School of Art a while back. I really enjoyed working in colour with Nupastels on newsprint since my days in animation school so I figured I'd give this a try. Got really inspired to mix it up when I saw Kay Huang doing some incredible, inspired and energetic work during and extra life drawing class.
