That gliding shot is one of the coolest shots of the creature in the film.
As to the Covenant variation of the design. Honestly it just looks like ADI doubled down on their previous designs. All the biomechanics are stripped out. Whether that's intentional or not, it takes away one of the interesting design aspects of the creature. Frankly, we've had enough of the pumpkin-head-o-morphs from A:R, AVP, and Requiem.
