Dear all,
I am sorry for this selfish request, but there's no one I could ask now, except for people in the Internet.

Could you listen to this video and evaluate my accent? What sounds are my biggest problem? I need expert advice.
Accent tag. Accent identification request. - YouTube

Could you also recommend a text which I could read for a video? There probably are some texts that are used by specialists to diagnose pronounciation problems.

And based on my current pronunciation where is it easier for me to move - to an American pronounciation or British or which one?

Thank you very much.
