I went for a softer more blended approach with Han's portrait. I find it quite scary at first laying in the first colours as they tend to be very strong but pastels are great in that nothing is too permanent and can be worked to a lighter hue or tone later.
I was intending to buy a new set of pastels today as my current set is limited in some colours. It can be an advantage to have a limited set but I'm finding that I want some more variety. I also want to try working with coloured paper. Unfortunately my local art shop has closed down so I'll have to wait to get more materials.
