Regarding research, creating a children's picture book is nothing different from the linguistic work mentioned above. Based on a deep text analysis, data collection starts for pictures. Gathered data will be categorised and critically analysed for use. I know many famous illustrators did/do research for YEARs to create a picture book.
Think of this ; if an illustrated picture should give inappropriate information such as too much generalised or stereotyped one. Yes, it's important to be aware of responsibilities of pictures. Thus, research for pictures is necessary and essential.
So, Friends, your research skills and academic background are great strengths to approach publishers and to work on projects.
My linguistics and sociology study definitely helps my illustration work. I've won Editors's trust in me. I always submit a text analysis for Editor/Publisher like an academic research essay. Then, Editor and I will discuss about a project and pictures more and profoundly.
This post might sound hard, but good children picture book illustrators are all good researchers with good writing skills -- is so true and not well known. In clear writing, Illustrator logically convinces Editor of her text analysis and greatly enjoys discussions over a text.
Back to the light topic, my dear linguist friend. Unexpectedly, my experiences as a picture book illustrator helped her! An illustrator pointed out a linguist's blind spot. The linguist would contact the team. Very happy! I heartily hope their project, too, will go well. After a long chat, the friend and I went to a beach for swimming. In turn, she helped me revise roughs for the education picture book project. With her help, I could reorganise roughs in a few days before a due date, this Monday. Yey!
In addition, "Friends Make Our Life a Party!" -- is also true!! Hahaha!
Friends, Happy Painting!
