Delacruz, nice set! Go for Landsoul's Horned Greathelm (H) or Broken Ram Skull Helm (H) to complete the set!
As for the cloak, I would go with something that has more red in it. Daybreak Drape (H) off of Tsulong is made for the red DK T10! Indefatigable Greatcloak from the Cata vendors in Org, goes well with red DK T10, too. Sorry can't provide any links yet.8/
