I have a question for you. I understand that when an artist does a portfolio for somebody, there are usually certain requirements for that portfolio. Examples: 10 to 20 finished work pieces, or sometime unfinished work to show process, one style or many styles, etc. I was wondering what qualifications you used as a professional illustrator in your portfolio when you were looking for clients. How did you handle your portfolio and how did you use it to show off your work?
