Ok fellow photographers, I've spent much of the evening working on my first serious attempt at a composite image of moving a subject to a different background. The biggest reason here is that I was trying to "save" a shot that I liked, but I overexposed to disastrous consequences. Even after fixing it in Aperture as much as possible, I was left with an ugly overexposed red car in the background that I couldn't do a thing about. So I decided to cut my model out from her background and plop her into another photo of mine that would be more fitting for her anyway.
So, here's the photo I wanted to "save":

And here's the background I found for her in my archive:

And here's the composite I came up with:

I don't think it's too bad for a first attempt, but I also know that I could probably improve it. Does anyone have any tips or advice on how I could improve on the image?
