Henri le Massif just looks generic. Please EA (*cough*) I mean CA. All you need to do is model a new helm crest for him. You can do it with existing assets. Grails and Lion crests models are already in game. All Henri's crest is is a grail flanked by four lions rampant... Shouldn't be too hard to resize an existing grail mesh and dup four lions around it.
Also can you also maybe add her shield to Repanse's back? She needs some colour on her model, the blue shield would help cut the all metallic look which is more associated with Empire Knights. Bretonnians have a softer, more colourful embroided look in general.
