What kind of accent do I gave and how strong is it?

Romanian

I’d say Italian or Romanian, it’s not strong because you’ve got a lot of phonological features of both American and British accents which obscure your native accent. I would imagine you watch a lot of TV/movies or listen to a lot of music in English because it skews a little bit more to American. You might have even lived in America for a couple of years. How did I do?

Whatever you did to improve your accent, it worked. You don't sound native, but you speak so clearly that it is hard to determine your native language. To me, that's what we all should want.
