loads of layers, for sure! the image is very rich, and everything blends together nicely. the only criticism that I would have is the font of the text at the top of the image, for some reason or another it isn't my favorite.
My image is not a composite, and its not quite a reflection either. well, maybe it is a reflection depending on your definition. anyways, it is a panned shot out the window of a moving vehicle. the smears of green might be caused from the reflection on the glass, I'm not quite sure.
