Yep, pretty creepy.

Layman's guess, it's the weird color scheme, white, pastel pink & deep Wizard of Oz Emerald City Green, juxtaposed with the subject of the piece apparently floating in some lonely black void. Which in turn may trigger the innate fear of eternal oblivion or being forever lost in an unreachable part of space.

The pen, pencil and paint roller all sold their souls to Satan in exchange for the ability to stand upright without assistance, formerly the sole domain of the rattle can.
Now their unholy alliance has him cornered and demands that the rattle can join them in service to evil, and taunts him over the newly established imbalance of power as he stands forced to pick one of two equally horrifying choices:

Join them and give up his ability to imbue artwork with soul forever
or
Be shoved off the edge of the tiny pixellated platform they all occupy, into a dark abyss of nothingness and despair.

The can stands parylized by fear, his formerly unique stability now a hindrance, hoping that the hand of The Artist will reach down to save him from Beelzebub's malevolent minions as they press forward...

"THAT FLAT BOTTOM ISN'T HELPING YOU NOW, IS IT, BITCH?...WHY DON'T YOU JUST RUN AWAY?...OH YEAH, YOU CAN'T BECAUSE OF YOUR PRECIOUS STABILITY!!!!MMMWWWAAAAHHAAHAAHAAA!!!!!"

NES developer here to fill in on some of the specs and why you might feel afraid. Compositionally the NES has a single universal color that counts as a free tile. Most dev's use black or white as it can bridge between all the hues. The system only has 12 colors to use at once for backgrounds (plus that universal color) and you can only pick from a selection of 32 defined colors. The one set in the 80' has little to no red and a lot of blue and green so often times you have to work within the limits of the system to make anything graphically interesting. You also only have 8kb of graphical memory bank to work with. The max that can appear on screen is 32kb.

So,
>Why is it so black? It looks like it's in the void.
Memory meant only a small amount of graphics could be used at once, so any unique tiles had to be minimal at best. The rest was used for free computational space or VBlank.
>The colors are soo ugly, why did they go with that?
The system's colors are stuck in a way which forced the creator to use tricks like dithering and attribute meshing which makes the image feel slightly off in some regard.
>Everything's really blocky and awkward.
Well, when your stuck with a system from 40 years ago it's a miracle you have anything on screen at all. Every pixel was hand placed, every portion of the image was considered and reconsidered to take up the smallest amount
of graphical memory. To the layman it might seem ugly or scary. To me? Well it's impressive. Follin's chiptune slaps, the games challenging, the art's subpar but there were worse on the system. I have and do boot Pictionary on real hardware just for the tune's.
