The voices need some variety.
There was no plot, which isn't a bad thing, but almost nothing happened. (Look back at you're last animation, it was short, but the plot and pacing was there)
And the audio is rather loud.
But for what it's worth it's alright for your second animation.

This is honestly pretty great for practice!

Fluid movement
Expressive characters
Even the characters are pretty personalized for no clothed stickmen.

Not to mention the great sound work!
Keep it up, your doing great!
(Try not to overwork your self into burnout as well)

The proportions are a little off in a scene or two.
But other than that, that was sick!

455 characters, and only one has delicious milk...

THERE I AM GARY, THERE I AM!

It pretty great, and fun!
I would recommend adding sounds and maybe music to add a little life to it.

Found this on YT, and I love how grand this sounds, couple that with the hyper nature of the OG theme, this piece is really amazing imo.
(Yes I know this remix is a decade and a quarter old)

It sounds a little cluttered, and a tad off-key, but it sounds pretty amazing!

Didn't even know this was 3D until the turn around started playing.

If you really think about it, this is one of the most depressing art pieces you made.

Unknowingly consuming the blood of your best friend, the bliss turns to dread as the realization sets in.

The patterns and shapes really please my eyes in this one idk why
