This was a cool challenge. Being able to see yourself working the tool closer to the targeted areas and then when it was time to push you couldn't see your tip at all. I didn't have the thick posca marker per the video so I just colored in a larger rectangle with the regular sized marker and then colored it in and let it dry before attempting the challenge. Made me really trust my muscle memory to make the intentional high spots where I wanted to in the colored area. After I was done I wiped off the majority of the marker and the results were satisfying in my opinion. One push was a little off but other than that it was pretty consistent.
