Oh, I wish I could draw beautiful nudes unconsciously like that. I wonder if we'll see this gag again on the future, it has the potential to be a iconic repeat if used well.
Mayu as character feels interesting to me because of her own aspirations to be a model. Makes me wonder if the author will take this as a opportunity to go a bit deeper on the trials and tribulations of making artistic modelling a possible source of income or even as a career (some people do it), and how that actually goes on Japan. I think there are many challenges that go beyond just keeping yourself phisically fit. I personally think this won't be the case, but I'd be very happy to be wrong.
As always, thank you very much for the scanlation.
