Nicely put together, Piotre. Personally, I don't tend to go for these sorts of things, as I find it a little frustrating that you never get to hear more than a few seconds of the complete song, but I fully understand what you've gone for, and I think you've done it to good effect, for the most part.
There are a couple of bits that I felt didn't work wonderfully well, and the main one is at 4:45, where the time compression (speeding up) can clearly be heard. Also, the pitch drop of the 'Now I'm Here' parts is quite pronounced, and sounds a little odd at first.
I love the One Vision part, though, and overall, I think this is technically a very good piece of work. At least you have tried to create something different, rather then just another stems mix, so well done for that!
Remember to deliver with the speed of light
A little bit of love and joy
