Fermat's Last Theorem: Now, this piano reduction of The Epoch - Wings of Time isn't exactly bad, but it sorely lacks in the originality department. JBWock was, indeed, able to reduce the segments appropriately for a solo pianist, but he lacked actual deviation from the source. As far as I could tell, the piano base (present in the original piece) was simply shifted down an octave and the melody transcribed exactly and superimposed. Any variation in terms of timing, phrasing, or note values would have been enough to make me consider adding a few points in the "Remix" and "Creativity" criteria. Likewise, an additional theme or perhaps a development segment would have been more than welcome.
Unpetitmax: This piece is very much like the original song from the game, and although it sounds good, I think the artist could have taken it somewhere else and played with the composition a bit. For example, I find the part between 1:04 and 1:30 to be quite playful, like in the original, but it could have been changed, expanded or otherwise modified in order to breath some new life to the piece.
Nyx: I thought this was a great effort, but it sounds too similar to the original piece. It's very simplistic, which isn't necessarily a bad thing. I do like that there is a bit of a jazzy feel in the piece, but it also sounds very tinny which is very detracting from the piece. Still, it fits perfectly with the theme of flight, but might be too simple for what I'd be looking for in a remix... and I generally love simplicity.
