Is this too confusing in a story?

I have two main characters and I switch between their points of view. The voice I use is different. One is more jerky and bumpy. I kind of repeat things. ex. 'He want to punch something. Wanted to punch something that would break.' For the other character, the words flow smoother and less angrily. ex. 'She didn't know if he was intentionally upsetting her, but she could not let her angry show.' Would this confuse or help the reader? My two characters are completely different, so I wanted to make that clear in my story.
