cool, whats the knight's story?
the shoulder-plates, and the medal, seem a bit out-of place tho, and seem too ''modern'' for a medieval knight. (i mean those red shoulder-guard-plates are a crystal sparkling red, and they have no damage or wear signs on them, unlike with the rest of his (awesome) armor and sword.
lastly, the sword is greatly drawn, but it needs a line in the middle to make it look more real, and to have the right depth effect(or the curving of the blade in the middle of every blade)
other than that, his armor is perfect, his face is epic and tired, and the cathedral is truly epic.
good work man!
