The tips I used for this project were the following.
Sharp Tip is what I use for outlining the picture and general purpose tasks.
The next is a shading tip to add depth and capture how the light creates shadows.
For the tight shading areas I will use the writing nibs to produce a more tight shaded line around areas such as eyes, beaks and noses.
I have a two output burning station so generally have the sharp tip connected to channel A and the shading tip connected channel B, so that I can transition back a forth without breaking my rhythm or train of thought.
