Zuko the Pyro

Just a quick sketch of who I think should be under the Pyro mask. I mean, it only makes sense that it's Zuko.
Reasons? OK, I'll give you reasons.
1) Zuko is a firebender. Pyro is a.. well, a pyromaniac. I don't think I even had to say this.
2) Zuko likes masks.
3) OK, I only have two reasons but let's just pretend I have more...
4)
5)
There! That seems like enough reasons to validate my opinion.
