This is a survey I answered for a student from my alma mater, BYU-Idaho.
What are your projections for this type of work or industry? Is it stable, growing, declining?
-The illustration industry is growing and declining at the same time. Many old avenues for illustration are dying (like magazines and newspapers, for example) while some are opening up. Through the internet, I follow the work of quite a few illustrators who do character design and background painting work in the animation industry.
