45 second ambient/wind intro; nothing wrong with that necessarily, and you have more than enough source usage to make up for that time, but there's very little development going on during on and imo it's just too long.
i think the piano that starts at :42 could use a sharper attack, and the sample throughout is just a little too exposed for it's own good. there are some really low notes being played, as will as some pretty thick, dissonant chords that muddy up the soundscape at times. it seems like it's in 4/4 the whole time, but the 'one-on-da-floor' rhythm doesn't really support the melodies, and the phrasing ends up a bit disjointed and hard to follow at times.
also, the piano sequencing is mechanical. needs more timing and velocity changes.
arrangement-wise, you've definitely expanded on the sources quite a bit harmonically, and the transitions/meshing of sources worked fairly well, however (and I will defend pokemon music to the death) these source tunes are pretty harmonically awkward to begin with, and that aspect of it has carried into your remix.
I'd have to go with a NO on this one, and I'm certain the panel would go the same way. first thing i would recommend fixing up is the piano sequencing with some timing/velocity edits. not bad, but there is still a lot that can be fixed or improved.
