As a fan of deadmau5 myself I loved this remake.
Yet there were admittedly problems with it.
Here are some tips for when you complete it.
-Give it more time
Half the enjoyment of Strobe is building up the song from the ground up.
Don't go headfirst into the middle of it or you miss the point entirely.
It's okay to not be exactly like the original but cymbals in a song like this just sound annoying. I mean really, it disrupts the whole flow of the song.
Try to keep an even balance between melody and rhythm. If you just put everything together at once, it will get tiring. At that point either end the song or make a bridge where the melody fades out, and comes back later. Like a breakdown of some sort.
I'm no professional but I think this song is great and if you get rid of the cymbals and well, make it longer, then the full version will be much better.
Btw I liked how the chords faded from ear to ear in the beginning - that was cool :)
