bundeslang - Good use of the melody but sounds hollow over all. It needs more depth.
NinjaPenguinDan - The style of this is unexpected in comparison to the original and I love that. Instruments could sound more real and the ending was as you said slapped on but really like the direction of this one.

It’s a tough choice, but I think I’ve got to vote for bundeslang. :P You did really well on this one, but if I may, there are a couple of small changes I want to recommend. The first is pretty simple: try adding a bit more dynamic variation from section to section. The first (and probably the easiest) method that comes to mind is merely tweaking the volume and velocity of the various instruments. There are other ways to do it, but that would be a good starting point. I think the only other issue I have is the dissonance at the end. I’m not really opposed to it, but my problem is that you never seem to resolve it. When it reaches the end of the song, I was expecting that dissonance to give way to a more consonant bit. It never did, though, so when the song ended, I was left waiting for a part that wouldn’t ever come. Thus, I felt sort of disappointed. It’s entirely possible that you wanted it that way, and I do respect that. Still, I believe it’s worth considering.

PlanarianHugger, may I recommend that you get some nicer piano samples? If you can't afford some of the really fancy ones, I’d suggest, oh, I don’t know… “Piano in 162,” maybe? It’s, like, 5 GB, but if that’s an issue, there are a bunch of free sample libraries out there. Just find one you like and roll with it. Aaaand that’s about all I’ve got for you. All comments aside, excellent work!

NinjaPenguinDan, is that supposed to be music?

(voting myself 2nd and 3rd to correct for the voting bonus)

PlanarianHugger - Song sounds complete. There's much stuff in the background, I like that. The song misses variation with the main samples, but I like the way you used the source.
NinjaPenguinDan - Good intro. For a 'speed entry' it sounds great. There's a lot of stuff in the song. I like that whistle.
