For my working method I am learning about color as well a good composition along side foreshortening. I am sketching out different bodies in different views to understand foreshortening and some color theory.
I have done sketches and some and some detail sketches, so far I am working on studies to understand foreshortening, and will move on to other detail sketches because I still feel unsatisfied with the ones I have so far. I will be working digitally for my value and colors and for my final I will be using water color, color pencils, and airbrush, with a little retouches of digital work.
