Luffy improving his haki level in battle is amazing. Finally Oda cleared that "inconsistency" that Busoshoku Haki now turns the surface black; Sentomaru, the Admirals and Rayleigh demonstrated a truly advanced level... hopefully Luffy does so as well. I want to see a Shanks-level Haoshoku Haki for once.
