I noticed in one of the earlier lessons he was pronouncing the ר like a guttural R.
Look up “Guttural R” on Wikipedia. It says this:
“In Hebrew, the classical pronunciation associated with the consonant ר was an alveolar flap, and was grammatically treated as an ungeminable phoneme of the language. In most dialects of Hebrew among the Jewish diaspora, it remained a flap or a trill.”

I’m just a beginner when it comes to Hebrew but you seem to pronounce the supposedly pure vowel “oh” sound like an English diphthong “ou”. Is this standard for Israeli Hebrew? Also, I noticed you pronounced the “ר” as an English alveolar approximant (thick American “r”). Is this common for Ashkenazim in Israel, or just American jews? I thought you were supposed to pronounce the ר as an uvular fricative or trill.
