Something along the lines of what I might draw in the margins of someone else's papers or on a receipt at work. The big difference here is this was done with my thumbs. Not the most nimble digits, they. I also made an attempt not to go with my now standard starting point of the eye. Doing the same thing all the time gets comfortable, and may be good practice to start, but is ill conducive to creativity. If sketches like these are to be anything but mindless ticks recorded on paper, the sketcher has to at be willing to be weird and forget his usual tacks. Sometimes, I am successful in these minor endeavors. It's a little harder using just my thumbs, though. Have been considering getting a stylus to remove such excuses, but first, I'll need money.
