I HAVE NOT PLAYED UNDERTALE.I drew this because my daughter was having a bit of an artistic block and I suggested that I drew my interpretation of the character from the pixel art, it might give her some inspiration (either things to do or NOT to do).This is based only on the pixel art and not anything about the game. The only thing that she told me was that it was intended to be androgynous so I tried to preserve that aspect. It shouldn't look male or female and be of indeterminate age. Hopefully I pulled it off, but either way it was a fun exerciseI'll probably play this eventually so please no spoilers!
