Please give me feedback for my school project !!! [SORRY NO GA]

A little pet peeve: at 0:27 you said Russian empire, then showed the Soviet flag. Moment later you referred to the 1905 Russian revolution, so the time was way before the adoption of the hammer and sickle.

I would suggest using some other names to compare him too. Especially in the range of kills and in his time.
Ivan Sidorenko has the same amount of kills (if not more) in the same era along with a few other russians.
The ones you mention have either less than half his kills or got them (Kyle) recently using better, more accurate and scoped rifles. In my opnion that's not really comparable. I would mention at least that more modern snipers / rifles provide a (relatively) safer way of working making having the same amount of kills less of an achievement (arguably).
Furthermore I would like to learn more about the person since it's a person-centered pice. Like, not just that he is from a farm (really does that make him a patient person?) but why he joined the military, why he was assigned being a sniper of why he chose to be, what decoration he received, his personality etc.

Other than that (prob most important) the music is annoyingly loud after 2:50 and it's hard to make out what you say because of that.
