I'm still much more comfortable with paper and ink, althought the digital work is slowly improving. I often start with a blue line layout, and then either lightbox it or clean up the original with a regular HB or 2B pencil. This time, I developed the blue line to the point that I decided to ink directly onto the layout.

Finally it was coloured in Manga Studio. I have to keep playing with these tools if I'm ever going to get any good with them. While it looks like airbrush in places, I've actually been trying something else, an approach someone told me about with Photoshop. You can overpaint an area on a separate layer (thank goodness for Layers!) and use hard and soft-edged erasers to refine and clean up the coloured shape.
