You've got a pleasant voice. In tune, nice tone. But to my taste you're singing a song that doesn't inspire me. I'd be interested to hear stuff you had written. My opinion is not very important because I am an old man and I think you may be aiming low, at a busker's audience. I think that a busker's audience would really love to hear something that made them think "Wow! Better than the original!" That would bring in the bucks, but is not easy to do. If you want to busk, then I think you should definitely go for it and do as much as you can; you learn from doing it and from observing the reactions you get. Good luck.
