Wow, everytime you come out with a new remix it's impressive how you take it in a totally new direction, stylistically. Before I even get into hardcore critique mode, I've gotta say, this is a cool and enjoyable remix
The intro to the track is pretty spotless as far as I can see. Sometimes it gets a little crowded in the midranges, you might consider cutting back on some of your synths a LITTLE bit, but not too much though. The mix is bright, chipper, and happy, and I like that
Your mix does tend to be a little stagnant though, reusing a couple of transitions and pretty much sticking with the same synth lead for almost all of the song. There was one point where you diversified it by bringing a different countermelody synth into the mix, but at that point it just felt like your melodies were competing with each other. I'd suggest doing some searching for possible alternatives to your lead just to give the song some variation.
Your piano toward the end, too, is just... really thin. You could try bypassing this with a bell/chime/music box sample that would fit the part well, or EQing your piano sample differently to give it a bit more body. Right now, it just sounds super-tinny, which is fine when it's surrounded by a bunch of other instruments/synths. However, in the outro, it's a lot more exposed and you can hear how thin the sample really is.
Aside from that though, it's a great track and I think it could be OCR material for sure. Very smooth beat, flow, nice relaxed synth harmonies... you just need to work on your dynamics and variation throughout the remix, and possibly fixing up that piano sample. Nice work, though! Keep it up here, I like what you've got going!
