No worries! That's what the thread's for. Don't be afraid to comment on any other feedback you receive over there, though. If you've got a lot to say, it might be easier because I know VMs have a really annoying character limit.
That said!
Anna's goal sounds interesting (although there's a hiccup with it that we'll get to in a sec), but it still doesn't quite answer the question of what exactly she studies. Putting it another way, think of it like this. Replace the term "Pokémon researcher" with "scientist" or "doctor." If you have a character who's a scientist or a doctor, that's cool, but it doesn't quite tell someone what their job is. A scientist could be an astrophysicist or a zoologist or a botanist, and a doctor could be a dentist or a neurosurgeon or a pediatrician. All of those occupations have very particular skills and interests. That said, if you have a doctor who's actually a dentist, they can't do the same things as a neurosurgeon, and a scientist who's actually a physicist won't want to be out studying chimpanzees in the wild like a zoologist would. Pokémon researchers all go by the same title (unlike doctors and scientists, for the most part), but they still study very different subjects that would require them to do very different things. Like I said in the thread, Professor Oak's interested in the relationships between humans and Pokémon, so he would study the interactions between trainers and their teams, but Professor Juniper travels all over Unova because she's interested in the origins of Pokémon, which she can learn about by studying Pokémon habitats and learning more about the connection between those habitats and the Pokémon themselves.
