It's really cool, big and strong set for one of my favorite Heroes.

But, if you allow me, in future (as you say that youre going to redo it) I think you should consider adding some changes to his Ultimate, improving his wings and / and halo, with maybe some nice sounds too (like the Priest Profession on Ragnarok: when you use Kyrie Eleison spell, some cool music plays).
I LOVED the Heart of Courage music on the description. One such epic music like that should be amazing to hear, every time this Sacred Knight Ults.
Consider it heavily, please. Nice work, PLEASE keep this going, as it could really fit into Arcana quality.
