Meh xd

Ok so first of all, the story goes by really fast. Like, the textbox where Jack asks Villager for candy is only there for like, 2 frames, or at least it felt like it. I had to rewatch and pause multiple times just to see what was happening. I feel like making more frames of the characters interacting and looping those frames a few times would help solve this issue.
Then there's the way stuff is drawn. To be fully honest, it kinda frigin sucks. I like how you did lighting, often a thing many people forget, but the rest Really needs improving. Like, this just looks very un-even ,with many inconsistencies, like Jack's left arm being a lil ,,leaking void", I would call it, while his right arm is a circular knob. You might wanna try removing certain lines and drawing them again if you feel they look bad.
The movements also look kinda janky at times, like the characters were shoved in from somewhere else, with a lot of small, white spaces placed around them during certain frames. If you ever spot this when animating, I recomend you remove those anomolies and maybe smooth out some of the character's outlines, since those seem to dissapear every now and then aswell.
And lastly, I understand that you have to draw a lot, like, A LOT to make even 4 seconds of an animatic, and it can take entire days. However, it's better to not rush yourself. There's a strategy I like to do, where if I'm unsure if something looks good, I leave it as is and work on a diffrent part, then when I can no longer remember how the thing I was unsure about looked I go back and can check if and what improvements it needs.

pretty cool man
