I particularly like the fact they kept to the original designs instead of going for the safer route of making a similar concept but "realistic" like most other adaptations do.
Like they yellow spots on Sneasel on that pic would be outright removed in other cases but (maybe because of TPCs autistic obsession with consistency) they had to be in.
Of course they all look better on the cartoony/anime style they do go for in the other media because that's what they were originally designed for., though Pikachu kinda feels like something that could've been outright designed for a live action movie. I guess that speaks about how good Pikachu's design is.
