Coloured Pencil Advanced Techniques

Wow - coloured pencil work using the advanced layering and burnishing techniques I've just learned is SLOW!  It takes hours and hours to do very little. Quite a lot of patience is required, which is a definite challenge for me. I'm starting to get a feel for it though - this is my first piece done completely solo - no tutorial. Not perfect, but not too bad for a beginner.
