It's been a bit of an adventure, but aside from the time constraints, said client has been among my most relaxed and trusting. And, as I mentioned before, they let me paint mismatched Lego people doing battle. So really, no complaints.
It's also led me to a rumination or two on some of the artistic challenges of illustration. Namely, aside from its end goal of communication of some point, concept, narrative or all of the above (as opposed to obfuscation, of course), illustration requires one to find imagery where one might not have otherwise looked or found inspiration, and to compose it in way that is compelling while still serving its source material, in this case a manuscript with a clearly defined philanthropic goal.
That, and in a forty page book, one has to thoughtfully pick out clothes for everyone.
Needless to say, while working on this, I've made little or no effort to pick out clothes for my own children. I should probably go make sure they've changed out of their pajamas.
