I have been working on this set for awhile, its not perfect but i like it. Didn't want to do full sets its more fun trying to come up with my own sets.
Since the OP is a blood elf, may I suggest a blood knight look. Get the tabard from the level 50 class quest, the shield from the first boss of heroic Hellfire Ramparts, any black and red armor to match, and you're there.
Flying mount that match pallys.
Sunreaver Dragonhawk from the argent tournament is perfect for blood elf paladins.
If you want to look like a real Paladin you will look like me. The rest of it looks like Nike designed it
