I would actually call it utility, as a defensive way of using it could just be standing still and creating the wall as a shield in front of him. Limitation with that could be the inability to turn on the spot, meaning he can't adjust his shield direction if he' is being attacked from the side unless he drops the shield, turns, and then raises it again.

Also, the short description should not include how he uses it, just what the base ability of the semblance is. So in this case, it would be that he creates a wall of aura that curves around him similar to a mach cone around a jet.

I'd also add a limitation that the wall can stop physical attacks but cannot stop energy/elemental attacks with no sustance. So fire could slip through the shield because it has nothing which can be held but earth would be stopped by the shield because it is a solid element.
