It doesn't matter if you're switching it... and please take this as a tip rather than me bashing your writing when you do it. But...

Please if you're writing in character's POV... don't see it as the easy way out. Seriously. I honestly feel like I can't read several fics that have a first person POV anymore because it isn't as descriptive. It doesn't matter if it's changing POV. But really... when writing in a character's POV... I normally look for descriptive stuff. Especially when it comes to internal conflicts. When writing in third person... it's better to actually elaborate on how the character is feeling and what their thoughts are. Sort of like how one writes their memoirs or autobiography. You have to actually be as descriptive as possible from things that the character is physically seeing as well. I want to be able to read it so I can become the character in a way... I want to be able to feel the same feelings as that character... know every single one of their thoughts... know what the hell they're seeing when they see a place, character, letter, everything.

Mianhae but... really this is sort of a pet peeve of mine when I read some people's fics that are in first person POV.
