Quick Sketch Illustration
Frames are often done a bit smaller in scale. Compositions are blocked in very quickly with the emphasis on the drawing, broader values, and the staging of the story. The detail is implied but not labored over.
The values are handled in a broader sense without a lot of rendering. Oftentimes, broad strokes will maintain an energetic look for the board overall.
This is a style that can be turned around rather quickly while still getting the job done. They tend to hold up very well in smaller formats such as letter-sized pdf boards.
