Struggling with the grey knight

I've been struggling a bit with this guy and been working mad hours, but I'd like some opinion on this I think. For some reason the photos all look awful, I'm sure it doesn't look that bad in real life! :(

Anyway, very very much WIP but do you think this is gonna end up working or is the pallet too blue? That's my main worry it's a lot of work and at this point it just looks like rubbish to me, but maybe I've been starring at it too long! :p

Would love some opinions!
