Casey Jones Part 2

Here's the "rough clean" and "final clean" of my Casey Jones sketch from the other day.  I generally clean up my drawings with 3B or 4B pencil right on top of the red line sketch, and then polish it up a bit further digitally (though, I suppose "final clean" is a bit of a misnomer, because I usually continue to tweak the line throughout the color phase, too).  Anyway, hopefully I'll find some free time to finish coloring it this week.
