I dont think its poor;y drawn it just needs to be cleaned up a bit

It's oekaki, dood.
Take it as it is.

It doesnt even have to be oekaki, it could just be a sketch the artist decided to color

Damn this perspective is very hard to pull off, i always need other drawings for reference

Somehow it feels like its originaly been a oekaki sketch with color and then someone has used a vector program to vectorize it and resize it to much larger.
