while i'm normally glad to see some coverage over these things, i do find myself flabbergasted over the crudeness of the final result. naturally, the quality of the art itself is impressive, but since it features heavily on leaked elements of the show itself, that's to be expected. although, i do know that there are plenty of characters such as a younger Luna and Celestia, not to mention other ponies, that aren't actually in the show in such form (or from certain angles) and obviously you did go to some good deal of work to put on a show that would appear appropriate and believable. that's not to mention some of the excellent 3D art featured in the video is quite beautiful.
on the other hand, the framerate is so hideous and chuggy as to make the video entirely unacceptable, nearly unwatchable. on top of which, not only are there plenty of points at which the frame-to-frame sequence short enough to honestly break a pony's neck if it were realistic in "any manner", but then there are points like 1:55 where a character is apparently dragged across the screen by some unseen force before he is forcibly twirled offscreen.
that's not to mention that there are elements of the Journal of the Two Sisters that defy canon anyway. they're few, but they're there, mostly due to the current build of the cartoon. i also fail to recall at any point when Starswirl was young at all: he was brown-bearded until the graying incident, but that's all, iirc. so you're taking a fair bit of creative liberty with the franchise to present Luna's Determination in memoriam.
and yet, through the whole video, i want soooo much to love it, but it's physically impossible. in fact, every second more i watch it just kill more of the possibility and i just wanna die on the inside. it doesn't befit the princess of the night. it doesn't befit Melodic Pony either, though i hadn't heard this particular work till today, especially if it's best to scroll away while i listen. essentially the star is for the effort, because that's almost all it appears to be. i can't really personally understand all the labour since i can't do the art, and i'm horrible at video editing myself, but honestly, i don't think i would feel right posting something as unfinished or unpolished as this. it just hurts people.
