This one is awful! Batman's head is so tiny. Compare his head to the size of his feet and legs. The proportions are so awful they make me feel uncomfortable looking at it.
I used to do something similar. If I touched something with my index finger, I had to touch it with my thumb.
The most noticeable example was adjusting my car stereo. I'd press next several times, or volume up several times, then I'd press it one more time with my thumb.
I've always followed the rule of 1 car length for every 10 miles per hour you're going.
