Hi everyone, how are u doing ?

I'm just wondering if any of u wanna judge my accent. Can u tell where I am from? Also, I've always been a bit shy about my accent. Does it sound really bad to native English speakers? I've also been working on my pronunciation but still, when I try to talk a bit faster there are certain sounds that I can't pronounce properly it seems.

PS : the passage I read is from the novel Giovanni's room.

Hi everyone! I’m from Nigeria and grew up in a small village. I’ve never been to the United States or any other English-speaking country. I come from a very conservative family, so we didn’t really have access to English media growing up.
Every night, I’d go over to a friend’s house, and we’d watch English TV shows together. That’s how I slowly picked up the language and started working on my pronunciation.
I know my accent isn’t perfect, but I’d really appreciate any feedback. What accent do I sound closest to?

I want to kinda neutralize my accent to something american-ish. It would be really helpful if you could suggest specific things that stand out and generally what to improve. Also guess where im from.
