Sorry, I agree with Jeff, the only word I understood was 中国. Even when I looked at what you wrote I still couldn't understand. 节 is pronounced jie2, but it sounds like you say 'yeah1' which isn't even a Chinese word. Maybe go back, slow down and concentrate on correct pronunciation and tones, rather than worrying about accent.

Sorry to say this but everyone here is too kind and it is not good for you. I cannot understand a word you spoke. if I didn't know what you had written. It's not the pronunciation nor the accent. [As a matter of fact, your accent is good] It's the tones. It is best if you invest in a digital recorder and play back what you said and then compare to a native speaker. You will then see where the wrong tones are.

It is good but it will be better if the tones aren't always go up. You know, the tone of each Chinese character may differ. Some go up, some go down, and some keep flat. Learn how to change tone for each word in a sentence and you will speak more better.

Really good! I'm not chinese but your accent is amazing. Congratulations. :D
