The plus side of her being one piece is that you only need to clean her up and glue her to her base - no fiddly weapon arms other other bits to glue on. The downside of her being one piece is that she's very two dimensional - I can't help but feel she looks like she's been squashed a little.
Aside from the squashed vibe, the detailing is nice, lots of fun folds to add some depth.
She's available from the Bombshell Miniatures store in the US and she is also cast by West Wind Productions in the UK, as with all of Bombshell Miniatures' pieces. I personally picked her up from The Wamp Store.
