I'm torn on the Earth subtype. It seems to make sense, yet delvers, which are similar, lack it.
Tremorsense 60 ft. like delver and xorn?
Comparing to delver once more (a Huge aberration) and elder xorn (Large outsider):
Delver: Str 27, Dex 13, Con 21, Int 14, Wis 14, Cha 12
Elder Xorn: Str 25, Dex 10, Con 19, Int 10, Wis 11, Cha 10
Current Denzel: Str 11, Dex 12, Con 12, Int 2, Wis 10, Cha 2
I'd suggest downsizing the delver's physical stats from Huge to Large, giving us:
Str 19, Dex 15, Con 17, Int 2, Wis 10, Cha 2
Dex 15 is probably too high, so I'd stick with 12, giving us:
Str 19, Dex 12, Con 17, Int 2, Wis 10, Cha 2
How's that?
