Sahaquiel is one of the seven great archangels and gaurdian of the fourth heaven, they're also called 'angel of the sky'
Anyways, funfact the Book of Enoch is about Enoch's ascent into heaven and transformation to Metatron, Heavens scribe! also Enochian the language of the angels is still a language you can learn to write in!
all these designs are for fun and practice, im just having fun learning about angels and doodling designs for them while im at it <3
