Wingdings Aster aka Gaster

My first time drawing an Undertale character and it's the mysterious Gaster.  Currently writing my first and probably only Undertale fanfic I call BeforeTale with Gaster as the main character.  Here his bio for said fanfic I'm working on:

Name: Wingdings Aster
Nickname/Aillis: W.D Gaster, Dr. Gaster or just Gaster
Family: Sans and Papyrus (sons), Arial (wife)
Monster type: Skeleton
ATK/HP: ???/???
MPP: ???
Magic type(s): Orange and Blue
Personality: Serious and logical at times but loves a good joke or a bad pun, very caring and kind to friends and family
Job: Royal Scientist
Background: Long ago Gaster and his family lived on the surface like all the other monsters before the war.  He worked for King Asgore with a fellow Scientist, a human named Dr. Richard Alexander, and is good friends with him.  It was Richard who gave him the nickname Gaster cause he said saying Wingdings Aster all the time was hard.  Back then he didn’t have the cracks in his skull until the birth of his son, Sans, when he had to use all his blue magic at once to save Sans’ life which left the cracks and gave him bad eyesight to the point he starts to wear glasses (which he somehow loses them when he fell into the void).  During the start of the war Richard was killed in trying to protect Gaster and his family, in which it sadden and upsets Gaster.

Other stuff: Gaster specks in two font types.  Wingdings - aslo known as Hands (which all mosnters can understand him) and Aster (mostly for humans since not all humans, his friend Richard included, can understand Hands)
