Hey Quinn, looking good, there. 
Comments on the editing:

[li]The cut from A to B is too awkward, because the angles are very similar. I’d make that one shot if I were you, maybe move the camera from position A to B.[/li][li]Something’s wrong with the cut from B to C, and from C to D too, but I can’t quite put my finger on it. Maybe it’s because all cuts are virtually from the front, so they’re not different enough - meaning, to the eye the object just “jumps” in frame. Try moving the camera in clip C, making the angle more from behind.[/li][/ul]Of course, that would ruin the “fin going over the head”, as you have now, and that would be a shame…
I dunno exactly what to do, but all your angles are from the front, with the submarine coming almost head on. Try three more individual camera angles. (but be careful about cutring from left to right side of the submarine, that would make the sub change direction in frame, and that’s called breaking the 180 degree rule
)
Cheers,
