Initially intended for the artbook, but decided against it after sketching them out. With the Toriel I wasn't satisfied with the proportions and with how I had drawn her (though I very much liked the face). With the Asriel... I was thinking of using it, but then I spilled ink across the picture...
I decided to slap some colour on the Toriel anyway as practice. Used the watercolour pencils again- it has a nice selection of pinks and purples, but I think I use a bit too much pink and purple in my art these days.
