its great to dream big, but those dreams should not cloud the greatness you have in front of you right now, consider the truth in the grass being the greenest right under your feet.
your foundation is nice!, there isn't any obvious mistakes..at least you know how to pronunce most of the words correctly, right?. however, there are some details you need to focus on..like intonation mentioned by monica above, is kinda so even or emotionless. if you want to make a break through, it's a good idea for you to begin to read slowly enough so that you got chances to discover mistakes you may never found before. correct them and practise to the best, then progress can be made~
