Can you guys give some feedback on my starter Pokémon? They don’t really feel enough like starters and I don’t know why

Ive been working on this fanmade region for a while now and even now, im STILL not satisfied with how they turned out. I don’t know if it’s the colors or proportions or Mabye they’re just over designed for starters but still. If you guys can give me some feedback it would be a greatly appreciated

For some more information:

Grass: A Cowardly and idiotic Japanese Serow covered in thorns

Water: A Moody Sea Krait whos body is mostly made up of water

Fire: A bold pangolin that attacks by heating up its claws
