Very well done. You have more of a British than American accent. Careful with the short 'o' in 'often' (the first one sounded a bit like the short 'u' in 'put' but it should sound like the vowel in 'not'). You could slightly speed up and vary the intonation a little. If you listen to each of your sentences, you can hear that you have used a very similar pattern for each one. Remember that we stress content words more than function words, and also when we have an adjective followed by a noun, we tend to stress the noun (unless we want to make special emphasis).
