CW: How would you recommend to other illustrators to get their work published?Read the whole interview.
Get out of the studio and make an effort to meet people. Be friendly and send lovely mailers that will be memorable and useful. Follow up and don’t give up. Volunteer to do work for your friends, their bands and any local spots that need updated graphics and images. Think of making small editions that use a narrative theme to show someone how you might work on developing a story across many pages. Do something different, but not so different that there is not a place for it in the market.
