While I agree with the rest of your post, this sentence does bother me a bit. Croagunk and Froakie are both frogs, but with completely different proportions and stylizations, as well as mostly standing on four legs instead of 2. I would say it honestly has more in common with Seismitoad, who shares a similar colour scheme of blue and a lighter colour, and has a more disc-like head. Otherwise, as I said, I agree. I have also noticed the designs seem to be a lot more simplistic, probably due to the backlash from the designs in the last 2 generations, and while it has been too simple before (i.e. voltorb, muk, poliwrath, slowpoke) i do miss the detailed designs of gens 4 and 5, even if the simplicity of this gen is somewhat refreshing.
