oH, Buddy already knows this trick, but, i can see how your video could work to teach a dog this trick!! and it was so creative, how you came up with this method on your own!!
We call it "Buddy, are you shy?" and he paws his face/eyes, with both paws, in sequence. It's not his best looking trick, though, he likes to do it too fast.
I've also just taught a similar trick, where Buddy holds one paw over his eyes for prolonged moments.....it sort of looks like a canine version of facepalm!!
actually, i taught this facepalm move as part of an informal heelwork/doggie dancing routine i am working on for a song, so Buddy will cover his eyes to the line, "I won't cry, i won't cry, No i won't shed a tear"

in an oldies song called "Stand By Me" by Ben E King. The hand cue for this move is my sort of wiping my own eyes.
I am now getting Buddy to do this cue, while in a beg position, but, my dog's "beg" (cue word "Wanna girlfriend?") is not the best, he can't yet hold that position for great lengths of time like some dogs can.
For the prolonged holding of a paw over his eyes, i used verbal cue "headache"
so i can ask, "
Buddy, does ___x_____ give you a headache?"

and work the trick into conversations with my friends, lol. Whatever topic we are talking about, i can ask Buddy his opinion on that topic!
I love to add
humor to as many cues as i can.

Most of my dog's tricks have a humorous cue to them, i don't much ever use the regular words like "rollover" or "speak" etc.
