A little side note no animator whether professional or amateur takes 3-4 months on a single animation, we all know that L&P is a compulsive liar but for his own sake he really have to control his impulses
Well... A high quality animation with complicated and detailed movement and lighting can take a long time to create. There are supposed to be 10 animations. Lets say 10 weeks total time for 10 animations instead of 3-4 months. So it is a nice round 1 week per animation.
There are way different levels of animations. In simplest terms an animation can be as easy as a person opening and closing their eyes to create a blink. That would only take 1 or 2 additional renders and a small line of code so the blinking is randomized a little bit.
Assuming what he says is true and the animations are out of this world and fantastic in every way... Long animations with great detail that are beautiful expertly made, and truly breathtaking of supreme quality...
I think it is a bad idea to have only... "Heavy Animations", and no "Light Animations" filling in the gaps. It's good to have some level of gradient when it comes to the animations.
With NOTHING to fill that huge empty void between a "Heavy Animation", and a "Still Render" that is just bad news. You need some short loops and blinks and other small scale animations like that sprinkled in as well.
A huge jump between stills and high quality lengthy animations is bad.
If there are no "Medium" and "Small" animations sprinkled in along with the "Big" animations then it feels so much like... hopping from island to island and it just doesn't flow as right.
If you have say "5 minutes of total animations" to spread out... Having that chopped into 10 huge 30 second long animations is a bad idea.
30 seconds x 10 animations = The animations...
Better would be something like....
(30 seconds x 5 animations) + (10 seconds x 7 animations ) + (5 seconds x 10 animations) + (1 second x 30 animations)
This way it would be 52 animations of varying sizes. It would still have those gigantic animations, but it would also have little ones too to mix in.
