I said this already in the comment section of the actual Youtube video, so I'll say it again here:
"GODDAMN!! 
It's enough this is clearly a nod to that one Levi's jeans commercial with "Pretty Woman" playing here, but to see a pink-haired mmd girl grow ala Gary Prenzo's GrowthDreams-dotcom is what REALLY makes this video, so far, to say the least...
...the BEST GTS video on Youtube!" 
Also, reposting it here for the still image preview.
