I spent quite a bit of time on this one, but it was worth it to illustrate the beautiful Tozer quote. You'll notice that I ended up not using the mop bucket and sign. It didn't fit with the aspect ratio restrictions of social media and made the picture look off-balance. In retrospect, I could have just shrunk it a bit and put it behind the custodian, which would have given more context clues to his employment.
The characters of the mother and custodian both came to mind pretty easily, but I struggled to conceptualize a construction worker in a way that didn't require a lot of extra set pieces (like the mop bucket). When I finally thought of a jackhammer, it was one of those, "Oh, duh!" moments.
I received a request to illustrate some gospel literature after I posted this, but at this point I just don't have the time or skill-set for it. Maybe next time, Oasis Vegas.
