There’s been a horrible mistake

Don't we have "Restricted Ability" tag of some sort? This being drawn with eyes closed.
Like those taking up the challenge, using either opposite hand or their feet to draw.

ART.

Cute.

So- nanoka-

Moe in the abstract

Isn't this how live2d work?

I disagree with the flag reason: If the challenge was absent I imagine the individual parts would form a coherent and decent piece.

Besides this can be considered abstract art: You need to weigh what the artist was going for vs the demonstration of their technique and style.
