I definitely like how this is split into different parts, like the different environments in a real journey. That opening part got me pumped, it sounded like the introduction to a really epic DnB action soundtrack...and then it wasn't, which was both a pleasant surprise and also a disappointing one. This journey through your mind sounds like a mess, and I mean that more in a good way than a bad way; it's artful. The dissonance and blatant differences in all of the melodies express how chaotic it must be in there. Sometimes the piano part, and especially that string sting, seemed out of place amongst a predominantly synth-based song. Other than that everything else is pretty cool, especially the beat and that beginning part. Nice work!
I liked the way you explained everything, and I'll keep all that in mind while creating the 'Part 2'.
