I finally admitted to myself that my old self-portrait is rubbish and I can do better now. I stuck with the greyscale because colouring things in is a pain. The water brush on Paint Tool SAI is my new friend - it helped make the hair look lovely and soft.
Have you ever drawn yourself? I've learnt that the only way to truly know a face is to draw it. You'll notice things that would have otherwise gone undetected, even if it's someone familiar.
