Here's what im aiming for. I have majority of it currently. A very Blood Elf set.
I went for the 'not letting go of his roots', heavily invested in the red of Silvermoon, and the green of their magic addiction, with the slight blue hues from the helm and weapons to represent his present state, a death knight.

Helm & Legs: ICC25h
Shoulders, Chest, Gloves, Weapons: Sunwell
Boots: Horde Pandaria JF Questline/TotC
Belt: DK Starter.
I could go with icc25h boots, but i wanted to keep the green tinge throughout the gear, as well as the red/grey theme. Most of the time i do not have my helmet shown.
The 2h weapon i use is the

Another possible shoulder mog would be the ICC25h DK set, as the blue 'smoke' of that helps the weapons. Plus it matches your helm, which i chose to strongly identify the death knight persona, as opposed to the sunwell helm. Personally, the h25 boots dont really fit in with the rest of the set. The cape in my opinion couldnt be more perfect in matching the red and the green. Tabard not required, just what i had on when i was doing MogIt, as well as the recovered scarlet onslaught cape. =]
