Workday Doodles

I found "rhythm" in my workday where I can do a little drawing. The pressures of the job have been interfering a lot more with my "art mojo", and the impulse to have that mojo express itself is showing.
Here's yesterday's sketchbook page. Each of these doodles was done on quick little breaks between tasks. I noticed some had fast lines, and others were a bit rendered or "noodled". This difference is probably worthy of exploration. The conclusion: there's something about being in a zone that artists can control, and I'm taking it for granted, letting it happen, which is my standard approach.
These are all impulsive doodles, so here they are.
