She's not actually cold blooded, and she has venomous snake slit pupils. She doesn't have the extra skin layer that most reptiles have in their eye lid.

Her upper body clothing is very much like [url=http://40.media.tumblr.com/bdd89ef3bc5ae82f1fc663cb41109527/tumblr_ngo928dJ811sgw570o1_500.jpg]this[/url]. Sure it might be a little warm, but not to the point of overheating.
Yes, when I said sling box I meant sling ammunition bag that you mentioned.

I'll change up her backstory so that it's more suitable. Her symbol was actually unchanged from her first iteration and I forgot to change it.

I actually have a new idea for her weapon, which I'll post on the Original weapons forum in a while after I tinker about with it. 

I'll be back with an update at some point today.

EDIT: Are there any problems with the Semblance? Or is it okay to leave it that way?
