Looking at those before and after scenes I'm thinking the text was actually clearer in the old one, not as stylish but definitely easier to read (new one seems a bit too aligned to the left btw), and I liked the lighter tone of color... actually, that applies for the lot of the scenes, I think the old subtle green was better than the improved (?) neon, and that more subtle coloring instead of the dark blue in the background for the room, and the lighter less obvious brown for floors. Color wise I'm thinking some things haven't really improved, but the shapes are definitely better, much smoother, and sceneries more detailed. I'm sure there's a lot of improvement in the motion too as the old characters look a bit square (that can't really be seen in the comparison)... but those colors man! Maybe change the palette a bit?
I like the lipsync in this; was surprised you even had some teeth included. That part felt surprisingly detailed compared to the sceneries... which I feel could be better. At many times there's just plain colors for backgrounds, when even simple shapes or lines would give the illusion of scenery. The floorboards look a bit square in the room, too, and lines overall are a bit squiggly. Looking at your newer animations there's a big difference!
As for sound, I feel the volume is a bit imbalanced. I had to turn it up and down depending on the scene. When the music's playing it's real loud and when some character speak you can barely hear what they're saying, a more consistent level for that would be great.
As for plot, that part was pretty entertaining. That final foot scene could've been a bit more intense, maybe shake the screen a bit when the foot comes crashing down? Include some sound? Something? Twas a fun watch though, keep it up!
