The only things I can really find are your Hammer of the Righteous Glyph and Ascetic Crusader Glyph, as both are really poor choices for raiding. The suggestions I'd give for your Prime are WoG or Judgment for minor gains in absorption shields, and for your major a Glyph of Divine Shield, which is useful for every fight with the exception of Morchok.
Personally, I do not enjoy Hallowed Ground as a talent in favor of Guarded by the Light, as I don't have any issues aoe tanking and I enjoy 80k WoGs in raids, but if you prefer your current setup there's nothing really wrong with it.
