If you hear the whispering of this dragon, pray. The beast knows nothing but death.

The whispering death is such a cool dragon, but the design falls short, especially the goofy head. Here's my take on a redesigned whispering death.
The spines point backward rather than randomly. This helps to keep most rocks and dirt from sticking to it as it tunnels underground. Dirt that manages to get through the spines is swept away as the dragon constantly sheds its scales, something it weaponizes as its ability to shoot its spines.
The wings are too small to grant prolonged flight, instead giving short bursts of flight when the dragon is rarely above ground
