This was my warlock for a D&D campaign. I'm not terribly fond of the 4th edition dragonborn design, my biggest peeve being a lack of tails. They're dragons, they most notably have tails. Tieflings get tails. Whatever.

He's an old school steel dragon (2nd edition lore!) and thus breaths lightning. I used a few different references for the armor design. A million points to anyone who can guess what the final armor design was most heavily influenced by.
