|I've never really been a fan of the armor sets from the three Orders, but you are actually able to make it work here. Nice look!|
Now for some critique:
Personally, I rare like to only rely on one or two colors. Might I suggest adding one different color, like charred dye? It would (to some extend) match up with your use of Twilight and Shadow Longbow.
As for location: As good the heart of the volcano in Mount Maelstrom is, I would also have liked to see images of you on top of it near lava flows.
Also new places from LW season 3 and PoF also have places with lava flowing. Just to name a few:
Draconis Mons, Siren's Landing and Desert Highlands.
These locations may help you get some variety and add the feeling that your Twilight Keeper is an adventurer and true lord of fire! :D
...I might've RP'ed a little too hard in the last sentence, I apologize. But again, nice look! :)
