Wow! A lot's happened since I last showed you what I was working on. I finally finished it. Here's what it looked like (yes, I said looked like)

These are the pictures I was working from and merging together.

As it turns out, the person commissioning the work had been misinformed about which child was the cousin and was to be left out, and which was the brother in the family to be left in and I had to do some fast and heavy editing at the last minute. But I managed to do it freehand with just a brush! I usually have to do a drawing first but surprised myself and here is the finished product which is now on its way to meet the family. (There's more to the story but for the sake of brevity that's the gist of it)
