I liked all the starters this time around, and here are my opinions on each of them:
Finally a grass starter that isn't a reptile. I like the color sheme and a Chipmunk/Chestnut hybrid sounds good. it has potential to become my all time favorite Grass starter. I guess he will have more spikes in his future evolutions and quite slender.
I guess Grass/Dark( for collecting nuts/Stealing) or Grass/Steel (Armour, think Ferroseed-like)
One more starter with a brilliant color sheme. I like the slender design and this is my favorite Fire starter since Cyndaquil. I guess it will evolve to become quite sleek and elegant, and the fur in its ears might even become real flames. I think Fire/Ground( since fennec foxes live in dry areas, bad typing but I see it fit)Fire7Psychic (it uses a psychic move) or just pure Fire. (
Anything but Fire/Fighting is fine really)
This is the one I like the least, and I usually like the Water starter the most. i think we have enough toads and frogs already (Poliwag, Croagunk, Bulbasaur, Tympole). I also don't favor the coloring as it looks plain. I hope the evolution change the main color to a darker shade of blue. Anyway I am not going to say that it looks bad, but it is my least favorite. I guess it will evolve into Water/Psychic(just because) or Water/Ice (it fits the current color)
Anyway I am really happy and this is the best looking starters since 2nd gen in my opinion
