Looks good - minimal errors, and only minor ones. I agree with you. I think people can make good progress in learning a foreign language from their native country, as long as they are dedicated. Although, you will miss out on some topics and may not see certain "everyday" words that you would otherwise see living in the country where they speak it as the native language. For example, I almost forgot the Russian word for "slippers," since you don't really use that word often when conversing with someone on Skype/phone.
