Blood Angels VI

I have assembled the sanguinary priests and blue tacked my Astorath together. Pleased with all of them, just need to add detail like purity seals and do the bases. I really haven't decided how to paint Astorath yet. I am torn between classic chaplain black, bone white, or a dark red. I need to make him stand out from the rank and file but still not sure how. Any suggestions?

Updated: I have reloaded the images, I loaded these from the Android blogger app trying to be clever, and it has done some odd mirroring effect on them!
