creating a reflection from the existing image presents problems with angles.
I used the transform tool to distort the reflection so that the feet and hands touch their reflections. I also roughly masked the reflection so that the far legs/feet wouldn't show.
I feel that this is more representative of what a real reflection would look like. I added ripples with the Wave filter, although Flaming Pear Flood might look a lot better.
