Killer instincts, awesome

Remixing the KI Selection track is ballzy, I'm not going to lie, so kudos for attempting the track. Considering what it is you actually make a fair attempt at remixing it. However...

You need some improved samples + less clipping in this track. Be especially careful with the bass drum, since it's over compressing the rest of the track to compensate.

The strings are weak with their slow attacks. The first note per phrase can use the slow attack, but using the slow attack throughout makes it sound very artificial.

The soundscape is hollow (half of it doesn't have a bass, even). It needs to fill the space more, be it through different instruments, textures, etc.

The arrangement is strange, considering it doesn't do anything for nearly a whole minute. If that's for singing that's fine, as long as you sing over it.

As it's set up, it's begging for a hip-hop vocal track. Because of this it sounds a bit unfinished. If you find a hip-hop singer to lay down a track this could be a pretty neat remix. As it stands now it needs some work, but it's a good start.
