Great videos Juan!
Some of those shots look so real I wanted to cry.
Things I noticed:
In the bow shot
Valiant obviously has anti-torpedo bulges. She probably should have taken a few more to sink.
Torpedo hits are way overdone. Should be less explosion graphics.
Propellors always rotate outward, due to control issues with inward-turning screws.
Torpedo propellors didn't seem to be turning.
Sailors on surface ships' decks had proper-looking uniforms.
