Iconic initials and background, original animation, pose, and character design. Really smooth physics, shadows, angle, and lighting as well.
This could use some sound effects and music track to add to the tone.
I'm nitpicking right now so take this part with a grain of salt as it's not going to affect my review but the bottom of the second letter seems a bit too long and it's supposed to be at a more diagonal angle. Of course I can also see all the other subtle differences, but that one pet peeves me.
Regardless, this was extraordinarily well done.
