Thori immortal origins ragnarok

concept sketch of thori the third brother of lorekki, the oldest of the 3 brothers and the big bad ass of the younger 2.
in this story it is said that odin had valhalla drag him from the throat of his father because from birth his dark instinct was to just kill everything, and wanted to murder loki and and hel herself ,odin thought he might attack the realms after this, it took valhalla 1000 years to remove him and place him in chains deep under helheim.
until the day he finally breaks free to fight his father..or his brothers they say.
(and yes the next one will be the real drawing of him and with new tattooing)
