Looking fast applies to supersonic speeds. Drag physics are kind of backwards at speeds higher than the speed of sound. For subsonic a round front with a pointy back is more aerodynamic. Like a snowcone.
Kinda yes kinda no.
The front, yes. But a long sloping back causes drag because the air stays attached to the surface. You want the air to detach from the surface when you’re not using it to reduce drag.
But also aerodynamics are very complicated so blanket statements are usually not super accurate.
Detaching and becoming turbulent actually causes more drag because the boundary layer shrinks causing low speed air to be closer to the surface. Fluids are super non intuitive or i might be misunderstanding your meaning of detached. Dimensionless parameters make it even more non intuitive.
It looks aerodynamic but I bet it probably really isn’t. Fast-looking things are rarely as fast as they look.

Dis right here.
