I don't have much to go on him. The brown needs layering and highlighting, then I think it's just the base and the gold to do. After that I want to do a transfer on his banner, then the base rim and a varnish and he'll be sorted.
@Levenrack That's OK. The blue on a Crimson Fist is one shade darker than that of an Ultramarine, but it's not really noticeable unless you're super familiar with both. Blood Angels are cool too.
