Hi, Valda
Pretty bold move, I admire your courage
1. You have some problems with soft/hard consonants (they more like an accent but if you want to reduce it, here are the tips):
You sing - колоса - but you need to sing колёса
you sing послэдним but you need to sing последним
you sing нэ жди but you you need to sing не жди
you sing менья but you need to sing меня
however you sing сина but you need to sing сына
you sing бил but you need to sing был
you sing времья but you need to sing время


2. not important but if you want to sound more Russian you need to pay attention to vowel "replacement" in spoken language
the word кондуктор is pronounced as "кандуктор"
the word "опасная" is pronounced as "апасная"
the word "жизнь" is pronounced as "жызнь"

3. some word corrections
not мамечке but маменьке
not трясила but трясина

PS: nice top BTW
