Just a few things....
This is like an NES game! I can see Link traveling through the fields, with this in the background. You might want to let off a little of the techno background and a little more of the melody the piano normally plays.
Ah, originality rings in this piece, unlike the ones that are almost 99% the original tune with tempo changes and different drum beats that suck. Yours, on the other hand, actually took a large amount of effort and work to arrange, and it's got a nice beat while maintaining some of the feel of Coldplay. This would have actually gone really well in an old school NES game, like Blaster Master, for example. Nice job.
One minor downfall.
I liked almost everything about it except that the notes were wrong in the main riff (or whatever you want to call it). That sort of put me off because it's not ignorable, and made the song sound murky when the other instruments came in. However. I will give you extra points for your own spin on it at 2:54, I did like that.
I agree with DoubleMXX. I can hear the origional song 100% and then hear the remix 100%. Does that mean i have 200% hearing?
This is a pretty good song, you scored some originality with doing a remix of a different song as it is, however it sounds quite a bit like it was made with a cellphone, i would try to do it with more closely realistic sounds so its more of a techno remix rather than techno cover.
Please contact me if you would like to use this in a project. We can discuss the details.
