This is the thumbnail layout I made for the steam tunnel sequence that recently appeared. I usually sit in front of the computer to draw these, with Shaenon's script file open so I can alternate between reading it and sketching out the layout. The layout page gets taped to the drawing board for reference when I draw the final art on Bristol board. If I'm lucky that week, the layout comes out in one neat piece and I don't have to make too many changes when going to the final art. In this case, I ended up changing the layout of the panel where Chuck emerges from the hatch.
By way of contrast, here is what a layout page that doesn't come out neatly looks like.
This would be for the wall-climbing sequence in the next strip. Well, I figured it out eventually. These kinds of pages are good for shaping the brush point and for inking practice. Yep.
