Please tell me how bad my accent is. This is the text

The Right to Privacy

Taxpayers have the right to expect that any IRS inquiry, examination or enforcement action will comply with the law and be no more intrusive than necessary. Taxpayers can also expect that the IRS will respect all due process rights, including search and seizure protections and will provide, where applicable, collection due process hearing.

My accent is all over the place. I live in the US but my tutor is British. I am learning a hybrid accent. I prefer RP accent.

Any tips?

Now I can watch some films with subtitles, read texts(I think my level is about A2 - B1) and understand the main point, but I feel like I need somehow to expand my vocabulary. I tried to learn new words using flash cards and it's seems effectively. But too boring for me and I just can't do it. So, maybe you can give a couple recommendations?

I am a native English speaker and I love meeting people from other places in the world. If you have any questions about English, make a post in this community and I will do my best to answer your questions.
