So after looking at the colored sketch a bit more, I decided that I should try something else. The yellow oval in the background just looked too much like the iconic Tintin running with Snowy image that everyone has seen and if I wanted to do that, I should go ahead and just do Tintin and Snowy running. But I didn't, so I figured why not bring in another character as a design element. Almost immediately thought of using the Thompson twins! Perfect!
The digital drawing.
Digitally inked version.
Duplicated and merged.
I thought that worked out well so I just had to place it into the composition.
