XYZ animation

A few briefs ago i made this animation. It was for a brief in which i had to make an animation based on the letters X , y and z. I think i did a reasonable job, but im not too happy with the concept itself. i think the camera work is ok, but the animation in some places looks a bit off, this is because i used a heirarchy to animate and this wasnt helped by cinema 4D's automatic slow in and out aswell as its animation spline smoothing, i turned it off in places to make a more realistic animation though.

As for the timing, i think its ok throughout but at the end when the explosion happens i think it could do with a re-shoot.

The keyframes on this animation i feel are spaced out too much. The aniamtion is supposed to be slow paced to show the mecha's size, but i feel it drags out too much, in most scenes the keyframes are spaces around 30 frames apart, i feel this is far too much, and i should lower it to around 20 frames apart, which would place the keyframes i used in scene 6 would be placed at frame 0, frame 20, frame 40, frame 60 and so on.
