The screenshots have way too much stuff going on in them for me to criticize in-depth.
If you made this in a week-- congratulations, it seems like it took a lot of work


The issues I see globally are:
Differently sized pixels* (neon "kanji" symbols on the first screen, in which the directional stretching is very obvious in two instances)
Overt
pillow-shading (the red windows of the train in the second screen)
Layering pixelart with
non-pixel effects (the purple ambient light in the third screen). This 'muds' the pixelart.
Although, in a way, these add to the semi-chaotic, mish-mash environment that the cyber-punk setting is known for
(not the pillow-shading though)
About the animation:The animation on the final screen, as it stands right now, has a lot of expressiveness in the characters' movements (especially the fat fish),
but to me, it's painfully choppy. (Also, frames aren't evenly spaced, hindering the "flow" even further)
You should add some in-between frames, I think
(even if the rest of the game remains with similarly choppy animations, this could be considered like some kind of deluxe cutscene

)
It's probably one of the most important moments in the game (if not THE most important) so I think it deserves some attention.
Although, since the deadline is so soon, maybe you already don't have enough time...
You shoulda posted a couple days earlier! Since we don't bite and all...
*EDIT: Looking more closely at the 1st screen made me doubtful that the signs are actually of differently sized pixels,
but that's the impression it gave me when I first looked at it, so...
maybe the problem was their lack of color depth in comparison to the rest of the scenery

Either that or the fact that when you stretched them, they lost their apparent resolution... (I'm a mess at this)
