I definitely like the idea of different reflections for different stages, so long as they aren't too noticeable; with the Generation's Green Hill example, I felt like the green on Sonic was a little too overpowering, it looked like someone boosted the green level in photoshop a little too much.
As for their creation, may I recommend using the gradient mesh tool in Illustrator? With time and finesse, it comes up with some truly outstanding reflection results. Plus, once you have reflections in place, all you have to do to change the color of reflection is select particular points and replace the color.
