Grandma Weatherwax

That's Grandma Weatherwax, one of my favourite Pratchett characters. I was thinking of placing this in "fanart" but it's not really a fanart at all. Of course it's Terry Pratchett who created Grandma Weatherwax but the image is all mine, so I'm only inspired by the book - not copying an existing (drawn by somebody else) character.
She is a little bit younger than she should be, but we may guess this is the time when grandma was still in the process of learning how to play cards (in order to win of course)
