How can I improve my British accent further?

Hi all,
Obviously I'm not British but I'd like you guys to help judge my accent and give me feedback on how I can improve my British accent further. Also, does it sound natural or fake? Is it obvious that it's a foreigner imitating a British accent?
Please feel free to leave a comment and point out my pronunciation mistakes.
Any help would be greatly appreciated! Thanks!
