This is my recreation of sledgehammer:
http://www.nyu.edu/projects/ruthmann/PWYM/sledgehammer/#53cbh (edit: I think my settings were not saved. Please check the screenshot)
I created it by soloing the reference tracks and individual instruments in turns and comparing levels and panning.
First, I had to reduce the levels of the reference track because I found it easier to compare the individual channels that way (so I had more room at the top), so my levels are a bit lower than yours.
Then I in turn adjusted the levels for Shak, Drums, Bass etc. and at the end the panning. The easiest way for me was to mute all the idividual channels, leave the reference track running and then quickly soloing / unsoloing individual instruments at characteristic points.
My result is fairly similar to the ones already posted. In my opinion, PG voice does actually have the highest levels, the BG voices are actually set higher (but PG voice is still louder).
What I could not exactly set is the panning for the individual tracks, it's very difficult to hear differences between different settings when the instruments are already far to the left or right.
Here is my creative mix:
I increased the loudness of Guitar, Piano, Prophet and Horns in relation to the other sounds, I really like their sounds. I also changed some of the pannings. I think the drums and bass are too loud in the reference mix.
