I like it a lot. It is a very nice design and the size is good.
My only problem (and I have this problem with 99% of Auras) is that it's too flashy, there should be a static version where things aren't always morphing, a "calmer" aura. The reason for this is that it hurts the eyes after too long, when there's too many units, etc.
Anyhow 4/5
