The only thing I don't approve of so far are the Pokémon levels, some are 4-5 levels under from when they're suppose to evolve, this was something HGSS recently fixed like Rival having a level 16 Totodile instead of a level 16 Croconaw. (since it evolves at 18). Only wild Pokémon can be seen underleveled, but that's on rare occasions and should not be made into something common.
I think Torkoal is a better choice over Combusken(since he's too underleveled), since we're not going with the cowboy theme anymore. And even though Flannery had Torkoal as her main fire poke, keep in mind that Juan's main was Kingdra in Emerald, which is similar to Clair. Besides, not many good fire Pokémon to choose from anyway. And for Brooke, I think you can pick something better than Quagsire, I mean HGSS Misty and Crasher Wake have used him already, there's many water types to choose from, like Psyduck/Finneon/Corphish. Or you could use this as a good place to use a starter like Wartortle since it's evolved from level 16 and you can switch Wigglytuff to 15 or something. No reason we should be having such strong Pokémon so early in the game and restricting them to unnecessary levels.
Just trying to make sense here in terms of gameplay.
