>>5800623When I played GTA and I didn't know anything about art, I just assumed those weren't illustrations in the whole sense of the word and more like stylized photographs, which fits the game because of the realism.
They look like high quality 3D game assets. And that's part of what made GTAV popular (the realism).
So I don't think the artist is a hack and more like they directed him into making something like this.
