Even on the later images, his early Gen 3 art had similar looks: the lines softened and the watercolor look went away and he tried to make the humans more realistic but they became too lanky and managed to remain cartoonish because of that.
Plus, the non-game specific arts always have comfy settings like snowfields or a running trail in autumn. They're more like Pokemon lifestyle pictures than the game arts which are either key illustrations or images of battles.
