Please avoid @-ing specific moderators, as it's rather impolite. I'm not seeing a button on your website's example, and your CodePen still isn't properly linking the the distortion image, but I'm assuming you're looking to improve the distortion effect on the '0' in '404', is that correct?
It would be easier for us to help debug this if you updated your CodePen with the actual effect you're looking for—my guess is that the differences you're seeing in the effect are due to timing, scale, and that your image has a solid fill rather than an outline, but without a codepen properly showing this it's rather difficult to debug.
