Sounds good enough but some vowels seem stilted, especially "А" which is typically more relaxed in Russian. It is the manner of pronunciation that creates the overall foreign feel of your speech. Think Treebeard from The Lord of the Rings movie: sounds stragely rounded, though clearly enunciated.
Хитроумный should be pronounced as a whole. You have some trouble speaking "возвращался", the word is unclear. That's bad, beacause it is the only stressed syllable that is the most clumsy. And "ль" in "сильный" is unnatural, the same with "бе" in "забежал" - somewhat palatalized, but not enough. You seem to apply English type of rhytm to longer words. There's little "pounding" in Russian: for example, in "шашлыкОм" you really have weak syllables both for "шаш" and "лы", not a semi-stressed "шаш" and weak "лы", then heavily stressed "ком".

As for the intonation, it is mostly OK save for the rhythm of the speech in general. The only thing to pay attention is "Жил-был" in the first sentence: you'd better pronounce the two words aprroximately the same in strength, or even the first stronger.
