What I have learnt:
Improved hatching
Improving commitment to line with pen
Use of felt tip pens
Use of oil pastels
Placing still life within context; my instinct is to go in close filling support with subject, but now I recognize that I can also include context, although it does require thought
Acceptance of bright colour
I need to work on:
Those backgrounds
Subtle use of colour
Clean lines
Using (twisting?) perspective to show all the elements I want to without compromising design and focus ( ref Picasso and Nicholson)
