I've recently been doing some more funky strumming that involves muting the strings more often than I used to, and I've realized that I have a strange way of muting. Instead of using my palm, I tend to use the top of my fingers, which may not be a good habit. The result of that is shown below. Should I just embrace my rather unusual muting technique and patiently wait for strong enough callouses on the top of my fingers, or should I try to get into the habit of palm muting? If I should palm mute, I'd appreciate any advice people could give.
