Concept Art - Silverfire

Oh hey...my first Transformer OC (specifically for the Prime continuity).  I haven't figured out her bot form yet:  I have a general idea of the overall body, but not how the wyvern bits fit in.  Maybe it won't matter?  Considering Prime Transformers obviously use mass-shifting....

I can't say much about her right now, aside from:  
1 - she's not a predicon (in fact she really doesn't like being mistaken for one...much like *spoilers*)
2 - she has a twin sister, Nightstar (though her name is not set in stone yet)
3 - She freaking breathes dicyanoacetylene fire...but for obvious reasons she can't tolerate using it for too long (like only a few seconds at most...long enough to seriously fuck up any 'former that pisses her off though.  We're talking a fire that burns up to 6k Fahrenheit according to one source....9k according to another....yikes).
