Oops sorry I didn't think my comment would spark a bit of a discussion like this.
A bit late to reply, but when I first saw the drawing, I recognized Dai instantly, but had to 'squint' a bit to recognise Shoma and Yuzu lol. I knew it was them but I guess I haven't seen them drawn in this style too often. I think without the context of the entire photo, I might not have recognized Yuzu even. But then I guess that's typical of a lot of caricatures and cartoons of real people. The aim is not for an accurate portrait, so elements of a piece might come out as not easily recognizable on their own.
I'm no very partial to this style myself, but I do appreciate how the artist composes his work. And I think he's very effective in conveying the feeling and message of his pieces.
