This is a show of the process of my 20 minute tonal work in my first Ipad session. As you can see, I start off with a sketch, then refine it a little, usually around the face if it's quick then I progress to blocking in colours, before adding tonal values. Beyond the stages in this painting is where I'd start colouring using the overlay layer. It is noticeable that even with a medium where blocking in of shapes is more common, I still remain with a more linear style in my work. I find it difficult to stray from that, and that raises the question. Do I need to do more blocking in, or should I just stick with with a linear way of work through and through?
