It's not narrative. They are just a bunch of random images drawn inside some panels.
When I haven't drawn for a while for whatever reason, I rule out a series of panels on a page or two and start to fill them up with whatever. This time around it took me a while to sit back down at the drawing board after I sliced a significant piece of my thumb off while cutting bristol down to comic page size, so I really needed to exorcise the bad drawings and knock the cobwebs loose.
I draw heads, figures, etc. Some get drawn from reference, others not so much. This little exercise just helps me with my brain-to-hand coordination and gets me over the fact that my drawings are going to be sub-par for a little bit and to not worry about it. The panel format helps me get in the mindset of drawing narrative again.
After the last panel is filled I'm usually pretty damn ready to get back to my actual pages.
