Thanks for the comments guys, I am happy with her so far

And now, a few specific answers to people:
Polarbear53; I have no idea at the moment how much to charge. Any input on that side of things from anyone who has done commission work would be greatly appreciated.
Shawry: I was given 2 sketches of what the character looked like (no transformed mode whatsoever, just robot mode), and told to make her transform however I thought would work best; so the transformation is all mine. When the model is completely finished, I'll post a small animation of her transforming. And yes, she is indeed a Decepticon

AverageJoe: yeah, I laughed as well when I saw where the turbines were supposed to be, but that was in her original design
